Lock Out Unwanted Users ................

Want to keep people from accessing Windows, even as the default user? If you do not have a domain do not attempt this.

1. Open RegEdit
2. Go to HKEY_LOCAL_MACHINE\Network\Logon
3. Create a dword value "MustBeValidated"
4. Set the value to 1
This forced logon can be bypassed in Safe Mode on Windows 9x
