How to Disable or Turn off PIN and Picture Password Logon in Windows 8 Advertisement

First and farmost, its a stupid trick. Why anyone would want to do it is beyond me. But if someone wants to do it then here it is how :

To turn off or disable PIN and picture password logon, open run command (Win +R) and then typegpedit.msc and press enter.

 Now navigate to Computer configuration-> Administrative Templates-> System-> Logon. On the right side panel, you can see the option “Turn off PIN and Picture password logon”. Double click the option and select the button “Enabled”

Click OK and close the Group policy editor. If you enable this policy setting, a user can’t set up and use a PIN or a picture password.

Please note that Group policy Editor might not be available in all versions of Windows.
