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.

The solution is using softwares that find your production Keys.
I use this this software(The Magical Jelly Bean ) and it gaves me a 25 characters called Cd key. (it works very fast!). the characters should be the same as Product key, because the last 5 character was the same as my production key on windows 8(windows shows it as *****.XXXXX).
