I think I have a unique problem, at least judging by the lack of answers on Google.
I am using TuneUp Utilities 2010 and Windows 7 Ultimate (x64).
I have used the TuneUp utility to change my logon image - everything went as expected, the new image is set...however, on every other or third restart (or shutdown/start) the image keeps reverting to the default Windows 7 one. I'm not even sure where to start troubleshooting.
Mind you, this is the only program/utility for customization that I use. I have changed my logon screen on my desktop (Windows 7 Ultimate, x64) and it is working perfectly. I did a clean install of Windows 7 on my laptop, did absolutely everything the same way like on the desktop and yet the logon screen keeps alternating back and forth.
Any help would be greatly appreciated.
