To adjust the transparency of the Alt+Tab dialog, you need to do the following.

  4. Under the MultitaskingView subkey, create a new subkey here named AltTabViewHost.-Windows 10 create alt tab view host
  5. Under the AltTabViewHost subkey, create a new 32-bit DWORD value and name it Grid_backgroundPercent. Note: Even if you are running 64-bit Windows, you still need to create a 32-bit DWORD value.-Windows 10 new dword valueWindows 10 create grid background percent
    Set its value between 0 and 100 in decimals.
    0 - means a completely transparent Alt+Tab dialog background.
    100 - means a completely opaque Alt+Tab dialog background.
    In the following example, I set it to 50:Windows 10 grid background percent 50

The default look of the Alt+Tab dialog's background:-Windows 10 default alt tab look

The tweaked appearance of the Alt+Tab dialog background with Grid_backgroundPercent = 50:Windows 10 in action grid background percent 50

The tweaked appearance of the Alt+Tab dialog background with Grid_backgroundPercent = 0:Windows 10 in action grid background percent 0 -1 Windows 10 in action grid background percent 0 -2

    Background dimming is nice. I wish my favorite Alt+Tab replacement VistaSwitcher had it. I still use it as I cannot tolerate Alt+Tab. Task View is nice but not as nice as VistaSwitcher.

    The old Alt-Tab tuner allowed changing thumbnail size spacing.
    This page https://winaero.com/comment.php?comment.news.5 show that WinAero Tweaker also supports this, but I can’t see it (only dimming etc.)

      Because you are in Windows 10.
      The alt tab dialog doesn’t support the “classic” options in this OS.

    Mine wasn’t working at all (Windows 7), it only switches between most recent window and current window and never even shows the multi-window switcher, than while going through your tutorial, I discovered that it works when I use Alt + Ctrl + Tab. It still didnt’ work with Alt + Tab even after using your tweaker (and manually applying the key mods in Regedt32, which were not there previously). I guess I have to get used to using a 3-fingered “salute” just to switch apps, what a pain…

    Can confirm it doesn’t currently work (10.0.18362.476). Modifying registry manually doesn’t work either.

    The classic Alt+Tab Appearance looks cool in my new [© Microsoft Windows 10®™ (“19H1″ 10.18363.1016.0” “1909”)] Laptop! the basic feature about this Classic 2D Flip I like is that it shows any kind of operation running at the background even if it is not showing anywhere! it still works when I’ve opened any Modern Application, whether it’s Task View or Search, or Start Menu, or notification panel, it shows them as an just application icon with no name, except it shows Task View Title when opened task view!
    That good ol’ Settings or any good ol’ immersive app I open, it shows only application icon and it’s normal regular title! Just shows only the Unidentified application icon!

    With the AltTab classic appearance, you can also set the Columns & rows value :

    HKEY_CURRENT_USER\Control Panel\Desktop\CoolSwitchColumns
    HKEY_CURRENT_USER\Control Panel\Desktop\CoolSwitchRows

    that could be cool to add theses settings in Winaero / AltTab setting page ?
