I accidentally made all the users on a computer non-administrators. So no one can get past UAC now. The hard drive is also encrypted with TrueCrypt, meaning I can mount it on another computer but I can't use any boot CD kind of thing.
Does anyone know how to add a user to the Administrators group using the registry?
Another option - I have figured out how to re-enable the Administrator default account, but the computer won't let me login - it says I need to use a smart card.
Any ideas on how to deal with either one of these issues? Thanks guys.
I'm using Windows 8.1 w/ latest updates.
Edit: Don't want to decrypt the drive. You need to get past UAC/elevate to decrypt a drive in Windows, which obviously isn't possible under the circumstances. Using a rescue disk to decrypt the drive would require a large amount (read: 1 day+) of downtime.
