Windows 10: Windows 10 activation on new hardware

I have a digital licence of Windows 10 Pro on my old laptop that is practically unusable which I linked to my MS account. However, when I try to reactivate it on my new laptop it says that it can't find any devices that my account is linked to and doesn't list the laptop which has it. I'm a student and really can't afford another licence. Did anyone else encounter this problem and manage to solve it?

Windows 10 Tweaks

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

Activation on new hardware

In the activation troubleshooter, when it detects no problems or gets to the end screen, click "I changed hardware on my PC recently", and select the license that corresponds to your PC. You might need to restart your PC.

 

DOWNLOAD WINDOWS 10 NOW - Upgrade and ISO direct from microsoft

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?
