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.
Seems strange your Administrator account would be configured to use a smart card. What sort of setting is this in? – Ramhound – 2014-05-18T03:23:01.000
I have no idea. I'd really like to figure out how to turn it off. – Mark Williams – 2014-05-18T12:39:44.527
You could decrypt the volume, use a boot tool to remove the password, then encrypt again. Just one option – Moses – 2014-05-18T13:59:41.163
I could, but I'd have to use the rescue disk (because you need elevated privileges to decrypt in Windows), which would take like a day. – Mark Williams – 2014-05-19T12:46:04.070
