WINDOWS NOT GENUINE after installing Windows updates

Anybody here who knows the solution to this error message : "Windows not genuine" after installing updates from Microsoft, I already activated my copy of Windows 7 five months ago, everything is doing fine until I downloaded the automatic updates from Microsoft last night, I called MS customer service and they validated my Product Key and they said its a valid upgrade PK, tried everything like WGA diagnostic tool, changing to a new product key, rearming, clean rebooting, safe mode, phone activation, reinstalling the tokens, EVERYTHING....I even called the MS technical support, no solution yet and they even escalated my case to their Research Department. Please, anyone who might have an idea. It will be greatly appreciated.....

Welcome to the Windows 7 Forums.

Have you tried resetting the product key?
You can do so in command prompt, see method 2 of this tutorial:
Change Windows 7 Key | How to Change Windows 7 Product Key

Hope this helps

thanks mitchell but i have already done that...doesn't work....

Microsoft indeed seems to have some activation troubles lately - no idea when it will be fixed. Did they give you a new key?

you could try clean install again

You say you have tried WGA diagnostic tool, what does your WGA report say ?


(1. Download and install the MGA Diagnostic Tool:
http://go.microsoft.com/fwlink/?linkid=52012)

2. After running the MGA Diagnostic Tool, click
on the "Windows" tab and then click on "Copy to Clipboard".

3. Next, visit the following website and create a post in the
"WGA Validation Problems" forum and paste the
results of the WGA Diagnostic Data in a detailed post.

yeah, i called MS Technical support and was helped by a very friendly and patient and very good in English guy from the Philippines who provided me several turnaround...he gave me a new PK, even downloaded that WGA tool, even reinstalled the tokens...every possible solution.....he decided that he will escalate my call to their Microsoft Research department because this is the first time they encountered this bug.....If not for that friendly guy frm the Phils., I could have lambasted MS for this, he assured me they're exhausting all possible solution in order to help me with my case....

Interesting post.. Please keep us updated as to the outcome vjcolfax

The Research team called yesterday. They don't have the idea yet why this bug happened. YOu know what the technician did? He just reverted my back computer back to a restore point ( before I received those messages ), installed the updates and everything was fine then. Magic, right? But I and even Microsoft itself can't even figure out what caused the bug.

not magic - just make sure you do not install the messing update again or you are back to square 1

Interesting and Useful, thank you for the update. A simple system restore often does the trick. However, this may have also done it, in combination with the system restore:

even reinstalled the tokens...

The updates didn't work with your old tokens, but then the updates worked well with the new reinstalled tokens. Since this was an upgrade, the tokens after the upgrade may not have been the same as the new ones that you reinstalled.
