I am so confused. I have used numerous of loaders/cracks previously when my Windows 7 got the msg "Windows 7 is not genuine"... Before that, my Windows 7 version is: 7600.win7_rtm.090713-1255. After I used one crack program, although it will let my "Windows 7 is not genuine" and black screen disappear, but it has changed my Windows to this version: 7600.win7_gdr.091207-1941 FYI, I check the windows version by using the loader program. So, my current situation is: When I go to Control panel, it said my Windows has already activated. But why in the Windows Action Center in the Notification Area, sometimes it will appear: Backup Windows...This pre-release of Windows 7 is going to expire in 7 days...Please backup....bla bla bla... I am so confuse...What happened? Who can help me?
