Windows 10: HOW CAN I ACTIVATE MY PREINSTALLED WINDOWS 10

I bought this new LENOVO Ideapad here in Ghana from a shop that has preinstalled windows 10 on. I can still not activate the machine to date. Any help?

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

Preinstalled Windows 10 deactivated

Which version and edition of Windows originally came preinstalled on the computer?

• • 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 install Windows 10 Pro

To find out if you have the right edition installed:

Click Start > Settings > Update & security > Activation > Edition.

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.



If the Activation Troubleshooter says Home, then you will need to reinstall Windows 10 Home.

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?
