Windows Genuine Advantage Notification (KB905474)



'Blocked PID' is a rare error - and I can find no reference for your PID in Google.


This possibly means that your Key is a counterfeit one.



I would suggest attempting to use the Product Key Update Tool to re-enter the Product Key from your COA sticker.
