My Thumbnail Previews over Taskbar icons in Windows 7 is missing. After some research I have found that I have to go to Computer >> Properties >> Advanced system settings >> and check "Enable Desktop Composition". Yet I have not found this option in my Windows 7 64-bit.
Why is that and what should I do?
Edit 2 solved: I have made a regular system update to Windows 7 and the option has appeared with "Enable Desktop Composition". Still Windows 7 is not yet SP1. So I can say the problem has been solved.Thanks for everyone.
