How to Enlarge Tiny Taskbar Thumbnail Previews in Windows
There are lots of ways to customize the Taskbar in Windows 10 , and they’re worth taking the time to perform, since you probably interact with the Taskbar all the time. While some of these tweaks are simple changes in the settings, others require a trip to the Registry.
One of the most useful Registry tweaks you can make to your taskbar is to enlarge the thumbnail previews that pop up when you hover over an open application. By default, these are tiny and don’t let you see anything distinguishable in the window, meaning they’re pretty much useless.
You make these previews easier on the eyes with the following tweak:
Open the Registry Editor by pressing Windows Key + R and typing regedit into the Run menu. Remember that changing values in here can cause problems, so be careful while editing the Registry. Navigate to this folder:
Now, right-click in the right-hand panel and choose New > DWORD (32-bit) Value. Give it a name of MinThumbSizePx, then double-click on the new value so you can change it. The default value is 200 (pixels); 400 is probably a good baseline, but if you’re using an especially small or big screen you may want to try something different. Try a few numbers here to find the best option for you.
I wish windows was smarter about window size in explorer based on what I'm doing. Like if I'm looking at images I want a big preview.

Now just log off of Windows and log back in , and when you hover over an open program you’ll see the new and improved bigger thumbnails. If you’re not happy, just jump back to that value and change the number inside. Now your previews actually give you an idea of what’s in that window!
