Windows 8.1 Product Key and Activation

Anonymous

About a week ago, I downloaded Windows 8.1 from MS Store. This was an upgrade for Windows 8 which came installed on my new HP PC.

The download was successful and Win 8.1 installed. However, Win 8.1 did not get activated and I keep getting a reminder screen to Activate Win 8.1.

This Activate Screen asks me to enter a Product Key. It gives me an error code of 0xc004c003 which states that the activation server has blocked my product key. It also gives the last five(5) characters of the blocked product key.

Well, I never entered a product key during the upgrade so I'm not sure where the product key came from.

I did a web search for the last five characters of the product key and it appears to be all over the web.

I used an application that showed the last fifteen(15) characters of the product key in my PC for Win 8.1 and they match the product key that I found all over the web.

It's no wonder that MS has blocked this key.

My question is. How do I activate Windows 8.1 since I have no product key.  MS Store did not provide a key with the download.

    Also Shenan, in addition to the HP link for upgrading to 8.1, there is also a link from Microsoft that should also be of some help. That link is:

    http://windows.microsoft.com/en-us/windows-8/install-latest-update-windows-8-1

    It provides a step by step instruction for this upgrade, and advise for problems encounter in this update.  One codicil regarding the serial key issue.  If the end user has continued activation errors, then re-installation of the OS that came with the HP product will likely be necessary. My ProBook came with installation, recovery, and driver software for W7 and W8.  This is SOP for all HP computers. That being said the user might also reference this MS link addressing this issue from the OS support point of view. That being said, again I will be happy to assist anyone with continuing problems in any way I can.

    Microsoft. Sounds like an OE problem to us.

    Lol Shenan. Welcome to my world.  Sometimes you just have to put the computer away and breathe. We are all bound here by a common objective, which seem to have some amount of frustration built in. BTW, 697 pages of activity? I am impressed.
