Reinstalling Windows 7: Not a Genuine Version of Windows
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.
Next step (and all suggestions were reinstall) Reinstall. I haven't had to reinstall a PC or Server in years. No way. Well, I spent another hour screwing with the damn thing. No dice.
Reinstall I did.
Upon reinstall, I got this message. "Windows could not complete the installation. To install Windows on this computer, restart the installation." And I found this answer here: (Note: First step didn't work, but second did. Thanks!).
When prompted with error unable to complete installation:
Hit SHIFT-F10 to bring up command prompt.
Click File -> Add/Remove Snap-in... (Or CTRL+M)
Select Computer Management (Double click and Finish on Local Computer)
Double click Computer Management (Local) -> System Tools -> Local Users and Groups -> Users -> Double Click Administrator -> Uncheck Account is disabled -> OK
Now right click Administrator -> Set Password... -> Set a decent password to get started.
Now, restart. Should be good to go.
If this doesn't work try next step:
SHIFT-F10 to bring up command prompt.
type: CD C:\windows\system32\oobe
Make a generic account and password. hit finish (if it requests a product key and you have one, enter it now. if OEM/No key required, just finish). Set time/date. Finish.
Should be good to go. It wasn't good to go. I restarted. Logged in, went to Windows Update, and got the same message. I'm heated. Long story short turns out it was due to the fact that I upgraded the hard drive from a 750GB to a 1TB. Seems the old intel chipset driver needed to be updated. I checked out the Gateway site and it said it was up to date. Checked out the Intel site - same story. Oh crap. Went to HP see what they had for chipset. Voila!
Luckily, I had an image of my drive before the reinstall. I restored my drive from the image, installed the HP driver, and all was well. Windows Update worked again!
