May you don't need to do so if you're shure you've been making system-restore back-ups.
W-XP does so automatically, unless this option is turned off.
If so, you start your computer in "Safe mode with DOS-prompt"
(Preferably login as 'administrator')
Change directory-- using DOS commands -- to: (ignore any error-messages)
then type 'rstrui.exe'
If you're lucky , the System Restore screen will appear and you can choose a restore-date
before your computer got messed up. After rebooting you will be fine again !!
(it worked for me, and I got my system back to before i f**ked up Internet Explorer by trying to install
the beta version IE 7, using the 'iecustom.dll' patch on an illegal XP copy. After rebooting the system
it reported not being able to open 'explorer.exe', cause of unable to find 'normaliz.dll.
This usually means the end of your OS, for explorer is an essiential filesysten of anu Window-OS)
GOOD LUCK ! com-pie
