Disabling the cancel button in the password prompt

Almost all Windows system have an option of enabling multiple users on the same system and using the username - password  pair to authenticate the identity of specific users. Unfortunately, on older versions of windows, a user can easily bypass the logon password prompt by simply clicking on the cancel button. Hence, many system administrators have started forcing users to logon by implementing a small registry tweak 

1. Open regedit.exe.file

2. Search for HKEY_USERS\DEFAULT\Software\Microsoft\Windows\CurrentVersion\Run

3. Create a new string entry named NoLogon and set its data value to:

     RUNDLL32 shell32,SHExitWindowsEx 0 

4. Exit the windows registry and restart the windows session for the changes to be applied.
