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?

From Why can't I activate Windows?

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

 

License activation issue: Your windows license will expire soon

Windows 10 Activation reports your license will soon expire.

This can happen for a number of reasons:

• You copied a Windows 10 Pro off the Internet (usually a volume license - organization - key) and changed on a Windows 10 Home installation. Windows 10 Pro is not free. If this is what you did, you will need to reinstall the previous edition
  or version you were running. You inadvertently installed the wrong edition.
  • The copy of Windows 10 you download and upgrade from will correspond with the edition of Windows you have installed, if it does not, this is why you might be experiencing problems activating:

• Windows 7 Starter, Home Basic, Home Premium, Windows 8.0 Core, Windows 8.1 Core will install Windows 10 Home
  

• Windows 7 Professional, Windows 7 Ultimate, Windows 8.0 Pro, Windows 8.1 Pro will installWindows 10 Pro

If the edition of Windows 10 installed does not correspond with the edition of Windows 7 or Windows 8 you were previously running, then you need to reinstall the right edition.

Did you purchase the laptop brand new out of the box?

You might want to reinstall Windows 10 Home to resolve the problem.
