Window Hidie

Window Hidie is an application that protects your privacy by hiding active windows. It supports keyboard shortcuts and can automatically hide at startup.

No setup required, besides .NET Framework

The program's wrapped in a single executable file that can be saved anywhere on the disk, or copied to a USB flash drive to launch it on any PC effortlessly. However, you must have .NET Framework installed. Worth noting is that it doesn't make any changes to the Windows registry.

Show or hide windows using hotkeys

It adopts a clean and intuitive interface made from a large window that shows the currently running processes at startup. Window Hidie doesn't only identify the windows of running programs, but also various system processes, such as the jump list, Start menu, PC user photo, MCI command handling window, power state monitor window, and others.
All you have to do is select an entry from the list to hide or show the corresponding window with one click. It's also possible to refresh the window list, hide the tool on startup, as well as to reconfigure keyboard shortcuts for showing all hidden windows, hiding the active window, and toggling the app's display.

Evaluation and conclusion

It comes loaded with simple-to-understand options for ensuring your privacy when working on your computer, by giving you the possibility to quickly hide and show the windows of currently running applications. It worked well in our testing and didn't hang, crash or display error messages. Unsurprisingly, it used low CPU and RAM, so it didn't hamper the system's performance.
On the other hand, it may be difficult to figure out the meaning of windows which don't belong to running programs, especially if you're a casual PC user. Otherwise, Window Hidie serves its purpose.
