How to Adjust ALT+TAB Grid Background Transparency in Windows 10?

The Alt+Tab switcher (also known as Task Switcher) is a handy multitasking tool in Windows 10. When you press the Alt + Tab hotkey, Windows 10 displays thumbnail previews of all open windows that you can switch to by pressing Tab.

Window users commonly use this function to switch between open apps or windows. While it helps with multi-tasking, it also offers complete control over your device. Default grid transparency is set to about 85% opacity; therefore, the window open in the background will be visible through the grid.

However, if the default transparency level does not suit you, using this gearupwindows article, you can change the transparency level in the Alt+Tab grid box.
