On Windows 10, when you use Alt + Tab to switch windows, the grid background is black by default, and the background windows and desktop icons are displayed as shown in this image. This post unveils some hidden registry settings to configure how the Alt+Tab switcher displays.

Hidden Registry Settings for Alt + Tab
Hide Desktop Icons and Windows during Alt+Tab
To hide the desktop icons and windows in the background (so that only the Alt+Tab switcher shows up on the screen), here is the registry edit:
regedit.exeand go to:
- Create a subkey and name it as
- In the right-pane of
AltTabViewHostkey, create a REG_DWORD value named
- Double-click Wallpaper and set its data to
Make Alt+Tab Transparent
In the AltTabViewHost registry key, create a DWORD value named
Grid_backgroundPercent” value and set its data accordingly.
0 means fully transparent.
100 is fully opaque. You may set something around
After setting it to
0, here is how it appears.
If the window titles are not clear, you may want to set the opacity to
10 or more.
Alternatively, create a value named
BackgroundDimmingLayer_percentif you want to dim the background wallpaper (not the grid background) and set the opacity as required. Here I set the
BackgroundDimmingLayer_percent to 40% (decimal:
40), and here is how it looks.
Exit the Registry Editor.
There are plenty of other settings related to Alt +Tab, but most are trivial.
