Windows 7: Windows 7 not genuine

Hi, I'm running Windows 7 64 bit premium.
The disc was bought from Tesco's online.
The box and disc seem genuine.
The warning "Windows 7 is not genuine" has come up twice now, but when I click cancel everything is OK.
I activated it months ago.
What would cause this ?
Regards Graham

Was this the upgrade disc i.e. did you upgrade from Vista or did you do a clean install over XP?

This was a clean installation...no upgrade.

Do this for debugging purposes only and only if your copy is 100% legit. Download and run RemoveWAT and reboot twice. That will disable activation security (and nagging). That's a last resort and it's completely reversible. I would call MS first as they can probably solve your problem easily.

Thanks for the reply !
I shall wait for the warning to come up again, then phone MS.

The cause is probably the new tecnology that you downloaded to on 2/23, which allows MS to detect counterfeit more easily. Not saying that you are not legit, just saying that it is being detected as not legit.

Hello Brother,

1) If it says your windows is non-genuine and go online to resolve, agree to that and go online. In numerous cases, simply clicking on that button resolves the issue.

2) If you have a legit install (as it appears), download mgadiag.exe from the link below.

Run the tool. Click "Continue", click the "Copy" button then “Paste” the report into a reply message in the thread below.

3) In feb, MS pushed a new WAT update (kb971033) which caused several genuine systems to be flagged non-genuine. If you have this update installed (check in Add Remove Programs), then do the following to fix the issue.

• Find KB971033 and uninstall it
• Reboot and run CMD as Admin
• Type “slmgr –rearm” (without quotes) and hit enter
• Reboot once the command is completed
• After reboot, go to System Properties and select the “Change Product Key” option in the Windows Activation section.
• Re-enter your Windows 7 product key, it should successfully activate now
• Reboot

Hide KB971033 if it shows up again.

Good one!

F/Y/I. Every 3 months MS will check for the update in question. They have threated to cut you off from updates if not installed.
