Windows 10: Windows 10 Activation confusion

I have a laptop which it used to have Windows 8.1, I reset this laptop but I lost my Windows 8.1 License Key, so, I wanted to install Windows 10, I used the media creation tool to make a usb boot drive, I used it on my laptop and it worked, I did the usual setup for windows 10, and unexpectedly I have Windows 10 activated on my laptop.

(I used the media creation tool on another pc, but I selected to create a bootable drive for another pc)

For this other pc, I bought windows 10.

Am I sharing the license somehow? I have the same account on both of my device. Will I lose the license at some point? Can I decide where to keep the license if this does happen?

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

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

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?
