If XP Pro, open a command prompt...
Start | Run | Type: cmd | Click OK |
Type: systeminfo | Hit Enter |
Scroll up to Original Install Date:

systeminfo

systeminfo
http://www.microsoft.com/resources/d...ysteminfo.mspx

If XP Home, see the Created Date for folder Properties for C:\WINDOWS or
C:\WINNT.
