UltraHide Pro is a fast and easy-to-use application designed to help you hide active windows from the screen by triggering a keyboard shortcut. It also lets you specify a password required for unlocking the windows.

The installation procedure is common, thanks to the fact that it bundles intuitive options. As far as the interface goes, UltraHide Pro opts for a regular window with a plain and simple structure that shows all available options and hides nothing.

It doesn't put emphasis on its appearance but it's easy to navigate. The frame stays on top of other windows, and this option cannot be disabled.

So, you can configure two hotkeys needed for unlocking one window and all of them, respectively, as well as write the password that will be requested for completing these actions.

What's more, UltraHide Pro is capable of showing three fake windows instead of the real ones, in order to throw the observer off track. Another hotkey must be defined for this task.

The app can be asked to automatically run at every Windows startup until further notice. It can start at system login and hide notification messages. There are no other notable options available here.

We haven't encountered any stability issues in our tests, thanks to the fact that UltraHide Pro didn't hang, crash or display error dialogs. It had a good response time and left a small footprint on computer performance, since it needed low CPU and memory to work properly.

Although it doesn't contain rich features, this app delivers a simple and stealthy method for hiding active windows and replacing them with fake ones, as well as for inputting passwords for resetting these settings. Too bad it hasn't been recently updated.
