I just upgraded to Windows 7 (not a clean install) and I noticed a couple of problems that I'm hoping someone could shed some light on.
First of all, all of the default icons in Libraries are just plain folders, with the exception of the icon that has a blue picture in front of a document (the one you get when you make a new Library folder). Imageshack - 45084541
I have tried countless options including removing the IconCache.db various ways and rebooted. I also tried setting the icon to the default in notepad but it is on the correct value. If I make a new Library and set a custom icon, it is also just a plain folder as seen by Downloads or Games.
Secondly, all pictures, including Games thumbnails but excluding icons, have white boxes on the corners as seen here. Imageshack - 81085507
Both these things happen regardless of the image size.
And lastly, when I try to access the action center I get "The page failed to load." Imageshack - 31102587
Well, thats all I've found, and I'd be glad if someone could find how to fix these problems.
