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.
