Hey guys, sorry if this has already been mentioned or solved in another post, but i sifted through many pages and was not able to find a solution myself. Basically, i installed w7, used the ZLoader my friend gave me and activated my windows7. That one was 7Loader Release 5. I then proceeded to install 7 on my other comp, and gfs comp and a third desktop. No issues. Then last night (April 9th), Windows Update downloaded an update - "Update for Windows 7 for x64-based systems (KB971033), and when i got home saturday morning, my Windows version was no longer genuine. I used Daz's loader on all the other comps because i didnt have 7Loader, and it worked like a charm, no issues, but now after that update i can't get any of the loaders to validate my W7. Tried using the 7Loader Release 5, tried using Daz's v1.7.9, and even 7Loader by Cybernotic ver1.5 None of the above have worked, and im not sure if i should reinstall windows or do i have to do something else? Any help or guidance would be appreciated, and sorry again if this has been resolved elsewhere.
