For some reason my HTPC got corrupted and gave me the great message of "Not a Genuine version of Windows." - Great! After poking around for a few minutes, I saw that my Windows Update was no longer working. Oh Great! I spent an hour trying to restore Windows Update with various suggestions I Googled. No luck. Even went back to the Microsoft Technet site. Now, we're getting deep. Still nothing was working. I tried various fixes, patches, and registry hacks. No dice.
