I was having an issue in Windows 7 where by my taskbar icons were staying lit or glowing – Image Here. After doing some research and reading people bashing MS by using simple algorithm in the gui to query for the most dominant RGB value in an icon, and paint the icon with that color. I figured that this is a part of the explorer.exe process.
Solution
So open task manager, quit explorer.exe. File New Process – Explorer.exe. Problem solved.
Seems this is a rare bug in Windows 7… that happens to me multiple times a day, lol.
