Free Window Hider

Free Window Hider is a tool designed to quickly hide a list with specified windows of currently running processes by triggering a hotkey.

It comes in handy for protecting your privacy if you fear that someone may be looking over your shoulder when working on the computer. The utility has some intuitive settings for all user levels.

Installing it takes minimal time and effort, since there are no unfamiliar options, prerequisite software products, or third-party components bundled with the setup kit.

When it comes to the interface, Free Window Hider opts for a normal window that doesn't put emphasis on graphical elements, yet it has a well-structured layout that gives you an overview of all options put at your disposal.

Two separate lists can be created for hiding and closing windows, and it's necessary to enter a string of characters included in the window titles, in order for the respective process to be taken into account.

Moreover, you can modify the default hotkeys for hiding and unhiding windows, as well as for bringing up this options panel. Settings can be applied with the click of a button.

It used a low amount of CPU and RAM in our tests, so it didn't hamper the computer's performance. Unfortunately, it displayed some error dialogs when attempting to hide windows using the designated hotkey. On top of that, it didn't correctly identify some window titles by the keywords we placed in the list with strings.

We must also keep in mind that Free Window Hider hasn't received updates for a long time and likely has compatibility issues with newer OS editions. Nevertheless, you can test it for yourself, since it's freeware.
