How to Make the Windows Taskbar Thumbnails Bigger (Without Software) When you hover your mouse pointer over a button in the taskbar, Windows shows you a preview of that window by default, but that preview is usually really small. Luckily with a quick registry hack, we can make those thumbnails bigger. The great thing about this tip is that it doesn’t require downloading some shifty utility from some website that you probably shouldn’t trust. And once you’re done, the thumbnails will stop being tiny and actually be useful. How to Change the Size of the Taskbar Thumbnails Start by using WIN + R to open the Run dialog and then browsing down through to the following registry key: HKEY_CURRENT_USER\Software\Microsoft\ Windows\CurrentVersion\Explorer\Taskband Once you are there, right-click on the right-hand side and choose New -> 32-bit DWORD, name it MinThumbSizePx and give it a Decimal value of 500 or less. This value will be in pixels, as you can imagine. GO HERE TO READ MORE http://www.howtogeek.com/200952/how-to-make-the-windows-taskbar-thumbnails-bigger-without-software/
