I can't find the group policy, can someone point me to the required item, huh?

Question

Group Policies

The behavior is as follows, after performing a PC lock
CTRL+ALT+DEL > Блокировать
I can only log in under an account with an active session, neither from the built-in administrator, nor from another administrator account, when I try, I get the following:

Этот компьютер заблокирован. Разблокировать его может только администратор выполнивший вход.

I need to get rid of this, please help.
