Windows 10: Bought Windows 10 Pro upgrade through Microsoft Store, now stuck with "Activate Windows"...

I bought the Windows 10 Pro upgrade through the Microsoft Store yesterday. Since installing it and rebooting my machine, I am now stuck with the "Activate Windows" watermark.


Things I've tried after consulting the documentation:

• Dead end #1: if I open the Windows Store again, search for "Windows 10 Pro", and click "Learn More", I get "You're running a non-genuine Windows 10 Enterprise Retail". When I then click "Get Genuine Windows 10 Enterprise Retail", I get an error page: "We're not sure how you got here, but you can't buy this version of Windows 10 […] Code: 0x8000FFFFF".

• 
  Dead end #2: The purchase confirmation emails I received from Microsoft never mentioned any "product key".
  

• 
  Dead end #3: I point my browser to my order history at https://account.microsoft.com/billing/orders/, and click "Windows 10 Pro". This brings me to another error page: "We are sorry, the page you requested cannot be found. The URL may be misspelled or the page you're looking for is no longer available."
  

What should I do?

This is my first time using the Microsoft Store and so far it hasn't been a great experience.

From http://windows.microsoft.com/en-us/windows-10/why-activate-windows-10

If you upgraded to Windows 10 for free and ended up in a non-activated state, try following these steps:

• Go to Start
  
  , then select Settings > Update & security > Activation.
• Select Go to Store, and check to see if a valid license is available for your device. If a license isn't available, you'll need to buy Windows from the Store.
  
  Note
  • This only applies if you haven't made changes to the hardware for your device.

or you could hack it with a crack but please note this is always risky and you don't know what's in the hack

 

Windows 10 Activation (Insider)

I bought Windows 7 Pro OEM key from G2Play.net for 12€ to upgrade to Windows 10 Pro - worked like a charm but be advised if you buy a OEM key you can not download the Win 7 iso from microsoft and have to get it elsewhere.

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?
