How to - Tweak: bigger Alt+Tab for Windows

After enlarging Windows Aero preview thumbnails (see previous posts)... why not enlarge ALT+TAB previews?
This trick works on Windows Vista too.

You must create a new key in the system registry and insert several values... delete the created key if you mess something. :P

Let's start.



Find this key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\

under this key create a new key called "AltTab" (look my picture) and then insert these values (without quotes) as DWORD:


"OverlayIconPx"=23
"OverlayIconDXPx"=0
"OverlayIconDYPx"=0
"ThumbSpacingXPx"=14
"ThumbSpacingYPx"=14
"SideMarginPx"=14
"BottomMarginPx"=a
"MinThumbSizePcent"=64
"MinWidthPx"=12c
"TopMarginPx"=3c
"MaxThumbSizePx"=d2
"MaxIconSizePx"=15e
"TextBottomPx"=1f4

(Above values are hexadecimal!!! But you can select "Decimal" for edit them and see them in a "human" way)

The procedure is:

• Right-click in the right space of the "AltTab" section (the space where there is the (Default Value)) > New > Dword
• Put the name in the new item like "OverlayIconPx" and then double-click the item to set/edit the value.
• In the OverlayIconPx insert the value 23 (Hexadecimal)

This is my configuration of these values, considering that my screen is 1920x1080...

Look this picture!! In the brakets there are the decimal values

You can edit the values and click Alt+Tab for view your change in real time.
Open some windows (6+) to see the Alt+Tab GUI in the max extension.
