WinLock

WinLock is a small Windows tool created to lock the desktop and prevent unauthorized system access.
The application not only that blocks any computer activity, but it also restricts mouse movement to its window, so users cannot click on the Start Menu or the Taskbar.
There are no configuration screens and this can be only good news for rookies or for those looking for a very fast and simple lockdown utility.
The app lets you choose a password when you first launch it, but what’s more important is that it comes as a stand-alone executable file, with no other file included in the package. This means that it’s also portable, so you can use it on the go, without prior installation.
It cannot be killed via Task Manager because every time you open the built-in Windows tool to terminate the process, the mouse movement is still restricted to WinLock’s window.
Of course, no help section is included in the program and this shouldn’t bother you too much since everything so simple. What’s more, it issues a notification warning every time you enter a wrong password.
As a conclusion, WinLock is a simple yet very effective lockdown utility. It works impressively well on any Windows version on the market and doesn’t need more than one click to lock the workstations.
Those owning a multimedia keyboard can lock their systems even faster by assigning a dedicated key to launch the app and thus prevent unauthorized access automatically.
