WinLock

Whenever you leave your computer unattended it’s a good idea to lock the screen, and this is easily done through a simple hotkey command. Chances are others might need to use the same computer while you’re away, but you don’t want to close everything. In this regard, WinLock comes with the means to help you lock a single window instead of the entire desktop.

Lightweight and easy to use

The time it takes to get the application installed on your computer is negligible, with the last step offering to launch it directly. A pretty compact window shows up, showing you what it takes to lock a window, and how to unlock it, namely the default password you’re free to change on the spot.
Once you set up the necessary details, the application window minimizes to the tray area, and you need to provide the configured password to bring it back up. A hotkey command is at your disposal whenever you want to lock a window. Sadly, it can’t be changed, but it’s both comfortable, and with a high chance that it doesn’t interfere with any other system commands.

Locked windows sent to the tray area

As soon as you hit the assigned hotkey to lock a window, the target item minimizes to the tray area and you can tell by the associated, default icon. Needless to say that trying to access it brings up a password prompt, and there’s hardly a method through which this security method can be bypassed.
A cool thick is to add a program shortcut inside the system startup folder so that it starts with Windows to have it ready when work begins. The only downside to the whole operation is that there’s no log of events to see attempts, or a method to lock the computer if too many wrong entries are provided.

In conclusion

Taking everything into consideration, we can state that WinLock is sure to come in handy, especially if multiple individuals use the same computer and one of them didn’t really finish a particular task. Even though you can’t change the assigned hotkey to lock a window, the overall practicality level makes it worth your while.
