If you don't have another admin account, what about using
"Administrator", the hidden emergency admin account? On Home, you F8
boot to a safe mode and in Pro you enter CADD at the welcome screen with
no account logged on and enter the password you used when you installed
XP Pro. If Administrator is the account you are using, well, now you
know why you shouldn't have done that. Every system should have
Administrator, another computer administrator account for routine
maintenance and a limited user account for routine browsing and email.
Three accounts even if you only have one user.

Did you disable SR? That is a bad idea and now you know why. But make
sure you run it anyway -- there might be an old restore point that is
better than nothing. You have to get a normal or a safe mode boot to run
system restore, but since it is only a user profile that is corrupt, you
should be able to boot.

That is exactly what occurred to me when I read that dumb article. If
ntuser.dat is corrupt, that KB article accomplishes nothing.

If that works, then that is the best thing you can do. Unfortunately,
you may have to reinstall your apps to repopulate your ntuser.dat
software hive. You will also lose your passwords and you may lose any
encrypted folders you created, unless you backed up your certificate.
How to Recover from a Corrupted Registry
http://support.microsoft.com/default.aspx?scid=kb;;Q307545
describes a three-step painful process to extract a copy of the registry
from the System Restore SVI folder, but it doesn't explain how to
extract the ntuser.dat file for a particular user. However, if you have
no restore points, this doesn't help.
