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?
You are using the release candidate software, this RC version is timebombed and will expire even if it is activated successfully upgrade to final RTM release
Sounds like a franken build, he correctly identifies the current build but sees the RC behaviour. I bet one of the many crack or loaders turned it into a franken build. (to the OP) Either way, time to collect your data, format and reinstal. Please see the repository and figure out exactly how you want to instal and activate BEFORE you do it.
