cleanitup

When i used the register tool from CCleaner it said that there were a lot of errors with the windows updates... I didnt trust it and made a backup. After that i clicked FIX. The next day I wanted to uninstall a program, but I saw that almost all the updates were gone from the list: in dutch they're named: XP beveilingingsupdate, I think its XP securityupdate in english...
