I installed the updates today. They did not install successfully, and the changes were reverted. So I restarted to try a few more times, no dice. Eh ok, I'll try again later after finding a solution on the internet. I logged back onto my account. The whole screen was black, and a screen came up saying my Vista Activation Key was invalid for activation. WHAT?! I typed in the exact product key on the bottom of my laptop in. An error came up:

Code: 0xC004F050
Description: The Software Licensing Service reported that the product key is invalid.

I have never touched it since I got my computer, and it was perfect ever since. PLEASE HELP!

I don't know about Vista but for XP some OEM versions install with their own product key, which is not unique, and the product key on the machine is just for reference if you call Microsoft or the OEM about your system, it shows that you have a legitimate installation. If you try to enter it or install with it you will get an error. You can install Belarc Advisor to find the product key for the actual installation. If it differs from the one on the machine that is the situation.

Genuine Validation under XP flagged some Volume Licence Keys up as being none genuine. A newer version changed this.

Under Vista, a new solution is here:

Thanks, the Belarc tip worked!
