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.

2015-09-04T15:14:59+00:00 Okay. Putting together the pieces you have provided so far... Making some assumptions . . .
You have an 'older' computer system (would you mind sharing the make & model?) Somehow (would you mind sharing how? Upgrade? If so, from what OS?) the system ended up with Windows 8 or 8.1 (which one? can make a difference.) installed on it originally and activated (how did you get it and how was it activated originally? How did you get your product key?) Something happened and you had to try to re-install. You (many assumptions here) decided to do a clean install of Windows 8.1 and when you attempted to activate, it failed. You then tried the instructions to activate by phone and the automated method failed. You then chose to speak to an operator and even then, the activation failed.
So, how much of that is accurate? Can/will you fill in some of the blanks to the story so we can figure out more details of where things could be going awry?

Did you get a phone number? Did you call? Did it refuse to activate? Did you speak with an operator? Did they refuse to activate?
