Since the testing of Windows 8, I've been using it all the way until the final RTM. I have to admit that M$ has really re-imagined windows and it is pretty fine . The problem is, the folder thumbnail cache is being reset frequently. This forces the recreation of the thumbnails which is irritating. I had always thought that M$ would correct this issue before the final release. This problem used to be in Windows 7 but was corrected later. I have changed the security information at the C:\Users\username\AppData\Local\Microsoft\Windows\Explorer so that the thumbnails are not deleted. I dont like this method. Is anyone else having this problem and what is the best solution if you do?
