If you mean Autoplay for your CD / DVD drives then from the files of WinXP
Pro here are the words of wisdom:
To change how your computer handles multimedia content
1.. Open My Computer.
2.. Under Devices with Removable Storage, right-click the device you want,
such as a digital camera or CD-ROM drive, and then click Properties.
3.. On the AutoPlay tab, click the multimedia content type you want to
change.
4.. Under Actions, click the action you want Windows to perform when it
detects the media type you selected.
Notes
a.. To open My Computer, click Start, and then click My Computer.
b.. Your removable storage device must be attached to your computer for it
to appear in the My Computer folder.
