Besides the ways that one can disable AutoPlay feature in Windows XP:
1.Registry Hack:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer]
"NoDriveTypeAutoRun"=dword:000000ff
2.Group Policy Edit:
Run\gpedit.msc >>Computer Configuration\Adminitrative Templates\System >> Turn off Autoplay >> Properties >> Enabled >> All Drives
3.Using TweakUI:
TweakUI.exe>>My Computer\AutoPlay\Types>>[Uncheck Boxes]
*************************************************************************************
You can also wholly disable all autorun.inf files from execution:
(No CD/DVD & Removable Drives show Autoplay context menu for the drive, nor they run it by themselves)
*Registry Hack:
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\Autorun.inf]
@="@SYS:DoesNotExist"
Note: To use the registry hack, copy all of the blue text above in a file with .reg extension (e.g. NoAutorun.inf.reg) and run it.
