!! make sure to use the hidden administrator only if you really need it. Deactivate the admin user after use. There is no password. Only hit enter. I would not recommend to change it !!

Open CMD as a regular administrator
activate hidden admin:

net user Administrator /active:yes

deactivate hidden admin:

net user Administrator /active:no

Start PC in "safe mode"
Login with an user whis has admin rights.
open the registry (regedit)
navigate to this path:

HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Windows NT\CurrentVersion\ProfileList\

Search the key which ends with ".bak"

Search the second key with the same name but without ".bak"
add ".old" to the key
remove ".bak" from the other key
on the right search for "state" and "RefCount" and add the hex-value "0"
close the registry and reboot the system. Now you should be able to login as usual.
