It seems a bug in Windows 7 and occurs randomly. It happens due to corrupt thumbnails cache in system.

To fix this problem, you just need to follow these simple steps:

2. Select system drive from the list where Windows 7 is installed in your system.

3. Now check the option "Thumbnails" and click on OK button.

    I'm so used to killing explorer.exe to fix a visual quirk, or some element not updating. Never even crossed my mind to use this. Almost panicked for a moment when even logging out did not solve the problem at hand. My 7 setup is pretty well customized, so almost wanted to believe something went horribly wrong Lol
