In Windows 11, when you press Alt + Tab to switch between opened apps and programs, by default the background is blurred and dimmed to the point that nothing in the background can be seen clearly. Many users find this to be a terribly unpleasant experience.
Fortunately, there is a couple of workarounds to disable the Alt Tab blur background in Windows 11. The method you will want to use depends on whether you want to also remove the dim effect in the background. If you want to turn off both the blurred and dimmed background effects when you use the Alt Tab task switcher keyboard shortcut, use the second method instead.
