Win 8: Lost all admin access through mistake in netplwiz!

I foolishly changed all user accounts to standard in netplwiz and am left with no admin access -- Is there a way to create one, or restore the original? thanks so much.

You can reboot in safe mode ( How To Start Windows 8 or 8.1 in Safe Mode ) and activate the built-in administrator account ( http://www.eightforums.com/tutorial...rator-account-enable-disable-windows-8-a.html ).

Once done log in as administator and either create a new admin account or change your previous one. Then disable the built in admin again...

Thanks so much!
