Difference from internal Windows XP computer lock feature

A lot of users believe that Lock My PC (as well as any other third party computer lock software) is useless because Windows XP has integrated computer lock feature.

Well, indeed, you can simply press Win+L on Windows XP computer keyboard and your screen will be safely locked. What advantages Lock My PC has over Windows computer lock?

  1. A supervisor can unlock the computer (with administrative password) without closing user session. If you use Windows XP computer lock, a system administrator can unlock computer but the user session will be terminated.
  2. If you share your user's account with others (it's common for home PCs), Windows XP lock feature is useless, because your folks will be able to unlock your computer easily.
  3. Unlike Windows XP, Lock My PC can display different lock screens (including transparent lock screen) - it allows to use your computer as a presentation machine - you can display your own information for your clients and nobody will access your desktop.
  4. Command line support allows you to use Lock My PC in Internet kiosks.
  5. You can lock CD/DVD ROM doors along with the desktop, keyboard and mouse - this can prevent CD media from being stolen while you are out.

Easy to use

Simply specify your password and the program is ready to use. You may lock your computer by hot keys or a double click on the Lock My PC icon in the system tray. To unlock, press any key and type your password.

Custom Lock Screens

You can create your own Lock Screen pictures and use it with Lock My PC. Your computer will look cool and unique when it is locked. You may use GIF, JPEG, BMP and animated GIF images as lock screens. Lock Screen transparency level option will allow you to vary the transparency from fully opaque to fully transparent. The latter allows you to lock keyboard and mouse only and may be helpful when you are watching films or running presentations on your PC

Stealth mode

Lock My PC can work in stealth mode. Stealth mode is a state when the program is running on your computer but does not show any sign of its presence in memory. In stealth mode Lock My PC does not show its icon in the system tray and is not listed in Windows Task List (Windows 95/98/ME only), available by pressing Ctrl-Alt-Del keys combination
