If you have big monitor with high resolution (1680×1050 or 1920×1080) and you have used keyboard shortcut alt+tab, then you may have noticed that thumbnails looks small and ugly. To get bigger thumbnails and icons when pressing alt+tab in Windows 7 use the following registry files:
- run windows-7-alt-tab-big-thumbnails-1680×1050.reg if you are using 1680×1050 resolution;
- run windows-7-alt-tab-big-thumbnails-1920×1080.reg if you are using 1920×1080 resolution;
- run windows-7-alt-tab-big-thumbnails-default.reg to revert back to Windows 7 default.
Here is an article that covers some of these registry values in detail – cybernetnews.com
