Windows 7 Build 7601 Not Genuine After Windows Update

To properly analyse and solve problems with Activation and Validation, we need to see a full copy of the report produced by the MGADiag tool
(download and save to desktop - http://go.microsoft.com/fwlink/?linkid=52012 )
Once saved, run the tool.
Click on the Continue button, which will produce the report.
To copy the report to your response, click on the Copy button in the tool (ignore any error messages at this point), and then paste (using either r-click/Paste, or Ctrl+V ) into your response.
- **in your own thread**, please
Please also state the Version and Edition of Windows quoted on your COA sticker (if you have one) on the case of your machine (or inside the battery compartment), but do NOT quote the Key on the sticker!
How to Tell

The tool will only give the barest results when run in Safe Mode - many things are disabled there.

See if this helps....

Please run a full CHKDSK and SFC scan....
type in the Search box
CMD.EXE
right-click on the only file that is found
Select Run as Administrator
- the Elevated Command Prompt window should pop up
At the Command prompt, type
CHKDSK C: /R
and hit the Enter key.

You will be told that the drive is locked,
and the CHKDSK will run at he next boot - hit the Y key, and then reboot.

The chkdsk will take a few hours depending on the size
of the drive, so be patient!

After the CHKDSK has run, Windows should boot normally
(possibly after a second auto-reboot) - then run the SFC

SFC -System File Checker - Instructions
Click on the Start button
type in the Search box
CMD.EXE
right-click on the only file that is found
Select Run as Administrator - the Elevated Command Prompt window should pop up
At the Command prompt, type

SFC /SCANNOW

and hit the Enter key

Wait for the scan to finish - make a note of any error messages - and then reboot.
Post an MGADiag report with details of any error messages encountered.

Great - please post an MGADiag report anyhow - it may still show up problems.
