WKey Disabler

WKey Disabler is a lightweight and portable application whose sole purpose is to disable the Windows key on your keyboard. You can use it if you frequently hit the respective key by accident while playing a video game or when working in a full screen application, triggering the taskbar display and, thus interrupting your activity.
As installation is not a prerequisite, you can simply drop the executable file anywhere on the hard disk and run it directly. There's also the alternative of saving WKey Disabler to a USB flash drive or similar storage unit, from where you can run it on any workstation with minimum effort.
One of the important factors is that portable apps do not work with the Windows Registry, therefore leaving your entries intact. Plus, files do not remain on the hard drive after removing the program.
Upon deployment WKey Disabler creates an icon in the system tray area. While it is active, the Windows key is automatically disabled, and its status returns to normal the moment you exit the application; you can do this by bringing up the WKey Disabler window and pressing the x key, or by opening the system tray icon's context menu. There are no other options available through this app; the previously mentioned window merely describes the tool's functionality.
The program is very light on the system resources, as expected, using a minimum quantity of CPU and system memory. No error dialogs have occurred during the tool's runtime, and the OS did not hang or crash. All in all, WKey Disabler is a program with minimal functionality, but it provides the simplest way possible to deactivate the flag key without taking any unnecessary risks, such as tinkering with the Registry.
