Trouble with fresh install of W7 Home Premium. After a couple weeks trouble free use it booted slowly and my desktop had reverted to the default new user desktop. A couple reboots later the old desktop was back. A couple weeks after that the same thing except the old desktop never resumed. All is fine now after re-imaging from an image taken right after initial install of W7 and a few apps.
Can’t find this trouble on google, but it was hard to format a good query to find meaningful results.
