Windows Desktop Lock is a small utility that will help you to lock your computer during your absence. The program's interface is very simple, but the program is unique in a sense, because it allows you to lock your computer without closing the open source program. While you are away, other users will not be able to interfere with other programs and make any changes to them.
However, it should be said that the program will be effective only for inexperienced users. For example, you can use Windows Desktop Lock to protect your computer from children. This utility is not suitable for better protection due to its low level of protection. Once you have entered your password twice and pressed the Lock this PC button, your computer's desktop will be replaced by a gray screen with a password field at the top and a button to deactivate the lock. However, by pressing such keyboard shortcuts as Ctrl+Alt+Del, Alt+Tab, Windows+Tab, Windows+D, or just a Windows button you can easily access the desktop and any program. That is, any more or less advanced user will be able to bypass this protection. The Windows Desktop Lock developer promises to fix all of these vulnerabilities in version 2.0, which is expected soon.
