Windows 11: admin account stuck at PIN setup, UAC only shows No

Hi Andrea_Catino, when UAC only shows “No,” Windows is basically saying there is no usable admin account available to approve the action. That can happen if the only admin profile is damaged or stuck during PIN setup. Try booting into Safe Mode first and see if the admin account can sign in there. If not, go into Windows Recovery, open Command Prompt if available, and enable the built-in Administrator account. Once you get into Windows with an admin account, create a new local administrator profile, move your files over, and then fix or remove the broken profile.
