It may indeed require a reinstall. I think on the wish list for Vista there
should be a F8 boot option to boot to the normally disabled administrator
account with UAC disabled. This would allow troubleshooting of UAC problems.
Currently I've seen a few situations where the fix is obvious but because
UAC is borked the fix can't be done.
