Accidentally lost administrative privilege

[jubair]

Hello guys,

Before enabling guest account, i tried to secure the system drive so that no one can access except administrator. Most probably i selected authenticated users in security tab. Think that's why i can't access. Now i can't create any other user, no access to device manager.

Help me out!

See here: User Account Password - Change from WinRE

Once you have enabled the hidden Administrator account from a Win 7 install disc, then you can login as Administrator to make any necessary changes to other accounts.

I've done this many times, works great.
