My 1TB SATA hard drive was replaced this week due to an imminent failure message on my Dell Studio XPS desktop. The repair shop confirmed the imminent failure and then cloned the failing HD to a new HD before catastrophic failure.
All looked good until I attempted to log into my Windows Live e-mail with the new HD installed. I got a pop-up that said Windows Live is closing because my calendar contains corrupt data. That problem is for another topic, but it led me to another pop-up that said my Windows 7 needed to be validated by Microsoft to see if it was "genuine," using the following website: http://windows.microsoft.com/en-us/windows/help/genuine/what-is-validation.
The result was that the Microsoft website said, "Install genuine Windows. Files that Windows needs to work properly have been modified, removed, or disabled. To resolve, you need to install genuine Windows. Not to worry, we can help you with that."
The Microsoft website offered to sell me Windows 7 Home Premium for $109. That would be fair if mine was an illegal copy, but my Genuine Windows 7 was purchased legally with the original PC in 2010. I don't know if this matters, but Start > Control panel > Systems and security > System, shows that Windows is activated and also shows the product ID.
I have run sfc /scannow. The result was "Windows Resources Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.log." Access was denied to this cbs.log file. Pease let me know if there is a way to validate my genuine Windows 7. Thank you.
