You have to establish a folder on you USB flash drive, such as "My PC.txt", the folder name ans extension can be modified. And bear the name in mind. And then create a folder on the desktop (logon.bat) and enter: if not exist f:\My PC.txt shutdonwn -s -t -c. The folder should be opened with note. Finally, enter gpedit.msc in the start menu, open the control panel of the group policy--windows settings--script.Then double click the log on--display file. Finish all the indicating steps and then click Add to finish your lock.

Have I made it clear? If not, pls feel free to ask.

Hi kerry,

You should download a predator for a start. Then installing run the application from Windows program menu or the desktop shortcut icon. Predator locks your Pc when you remove your USB flash drive even if your widows session is still running.It will darken your screen and the key board and mouse will become inactive. When you return back then just insert your USB flash drive and the windows will be automatically unlocked.
