This tutorial explains how to adjust Alt+Tab grid background transparency in Windows 10. By default, we see a grey color grid background when we access Alt+Tab or Ctrl+Alt+Tab mode. However, there are simple tricks using which you can change the transparency level of this Alt+Tab grid background. You can set the transparency level between 0 and 100.

I have done this with the help of a simple Registry tweak and free Winaero Tweaker software. In the screenshot below, you can see the default grid background, grid background with 30% transparency level, and Alt+tab with no background (full transparent).

Step 4: Under the AltTabViewHost key, create new DWORD value and name it “Grid_backgroundTransparency“. As soon as you create this value, its default value data will set to ‘0’, which means there will be no grid background at all in Alt+Tab mode. You need to change this value data between 0 to 100. Here 0 means no grid background and 100 means complete grid background.
