I have a Windows Vista system whose profile seems to have been corrupted. Many solutions seem to indicate that you create another admin account, log in as that account, and delete the offending profile information for the account that is corrupted.

Here's the twist:

There are two accounts on this System - 1. Administrator Account 2. Standard Account.

It's the Administrator Account which has become corrupted. If you attempted to do any user managment / attempt to create a new account under the 'Standard Account', UAC prompts for a user/pass. It has the admin account come up by default, and asking for a password (of which, there is none).

When you click 'OK' - nothing happens (no doubt due to the fact that the account is corrupted, so it can't verify who or what is trying to allow the administrative privilage).

Can anyone think of a way of fixing this account, or creating another administrator account to resolve this issue?

Many thanks in advance.
