I have resolved problem by uninstalling "file nesting" extension for Visual Studio.


This happened to me as well, what I did was I deleted all the iconcache and thumbcache files used by File Explorer to cache the icons.

The location for the iconcache and thumbcache different from Windows 7. I am on Windows 10 CTP, but I believe it is the same with Windows 8 or 8.1. For Windows 10 CTP it is at:


You will need to start an elevated command prompt and delete it from the command line. Before you delete the files, kill Windows Explorer process using Task Manager first.

Then delete all thumbcache* and iconcache*, restart your computer afterward. The cache will be re-created upon restart.
