Help! Lost users on computer

[BurningDesire]

So I have done something really stupid. I was trying to turn on the built in Admin account from Kali Linux. However, There seems to have been a error. All the other users on the computer besides mine are gone! There still on the actual computer since net user shows them all. I think some grouping went wrong. Even worse is now I can't remove the newly created admin account. I use SAM to do this.

HELP PLEASE

Edit: Please refrain from being a grammar nazi. I typed this fast because I am scared.
