Turns off the Autoplay feature.

Autoplay begins reading from a drive as soon as you insert media in the drive. As a result, the setup file of programs and the music on audio media start immediately.By default, Autoplay is disabled on removable drives, such as the floppy disk drive (but not the CD-ROM drive), and on network drives.If you enable this setting, you can also disable Autoplay on CD-ROM drives or disable Autoplay on all drives.This setting disables Autoplay on additional types of drives. You cannot use this setting to enable Autoplay on drives on which it is disabled by default.

Note: This setting appears in both the Computer Configuration and User Configuration folders. If the settings conflict, the setting in Computer Configuration takes precedence over the setting in User Configuration.

Note: This setting does not prevent Autoplay for music CDs.

To enable this ..

open group policy (start > run >type "gpedit.msc" and press enter )

Local computer policy > user configuration > administrative Templates > system >Turns off the Autoplay feature> mark enabled $ apply 

Speed Up Windows XP and Improve performance

1) Shutting down WinXP faster

When a user shuts down Windows XP, first the system has to kill all services currently running. Every once in a while the service does not shut down instantly and windows give it a change to shut down on its own before it kills it. This amount of time that windows wait is stored in the system registry. If you modify this setting, then windows will kill the service earlier. To modify the setting, follow the directions below:

Click on Start, and then goto run, type REGEDIT

Navigate to HKEY_LOCAL_MACHINE/ SYSTEM/CurrentCo ntrolSet/ Control.
Click on the "Control" Folder.
Select "WaitToKillServiceT imeout"
Right click on it and select Modify. Set it a value lower than 4000

2) You can start up without needing to enter a user name or password.

Select Run... from the start menu and type 'control userpasswords2' , which will open the user accounts application. On the Users tab, clear the box for Users Must Enter A User Name And Password To Use This Computer, and click on OK. An Automatically Log On dialog box will appear; enter the user name and password for the account you want to use.
