Yep. That's why often it requires rebooting to uninstall 
software. How can the installer remove itself? Under Windows 
95/98/ME, you have to manually add entries to WININIT.INI. With 
Windows NT/XP/2K, MoveFileEx() with a NULL target and the 
MOVEFILE_DELAY_UNTIL_REBOOT flag will add the appropriate 
entries into the system registry so that the next time the 
machine reboots it will remove the files specified. Its a real 
pain and a real hack of an OS.
