Windows 10: windows 10 activation key and download

I want to buy or get legally for free a copy of windows 10, but I'm confused.I see this link: https://www.microsoft.com/en-us/software-download/windows10ISOIt suggests I can get a copy of Windows 10 for free. I see others online saying that gives you the ISO but you still need a keyI'm not sure if I will then need to buy a activation key.I see vendors selling activation keys. I'm downloading the ISO from MS as I write this and am not ready to install to find out. Will I need a key? Is there anything to worry about buying a key from a vendor?By the way; If install Windows 10, and get it runni

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 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 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?
