AutoLock

AutoLock is a feature of Boot Sentry that allows you to automatically lock your computer after a set amount of time you specify.

If you wanted to let somebody use your computer for only a certain amount of time (say, 45 minutes) you could set AutoLock and then WinLock would start after 45 minutes.

To set AutoLock

Right click on the Light bulb icon in your system tray (the area by the clock)

This will open the SysTray Support  Menu. From there, click on AutoLock.

Enter the amount of time you want AutoLock to countdown to, in minutes. You enter any amount of time between 1 and 120 minutes (2 hours)

Click OK

AutoLock will then start counting down the time left until it locks the system.
