I got it fixed 

There was a 'troubleshoot' option and it changed the license to the one that is already linked to my account

Which version and edition of Windows 10 originally came preinstalled?

 If you took your computer to a repair shop, they might have installed a non-genuine Windows 10 license. Either the repair technician didn't know which edition originally came preinstalled or made an assumption; or installed a copy that bypasses Windows 10 activation technologies.

You copied a Windows 10 Pro or Enterprise key off the Internet (usually a volume license - organization key) and changed on a Windows 10 Home or another edition. Windows 10 Pro and Enterprise are 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 should often 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.

Windows 10 Home Edition also Reports Organization Activation Service

Windows 10 Home is not immune from the organization key errors too.

The error can occur for a number of reasons. It is possible, the OEM vendor might have used a OEM volume key to mass activate each machine imaged at the factory with Windows 10 Home. Users can try recovering the OEM Marker key embedded in the motherboard then use it to update the product key values.

Press Windows key + X

Click Command Prompt (admin)

Enter the following command:

wmic path SoftwareLicensingService get OA3xOriginalProductKey

Hit Enter

The product key will be revealed, copy the product key then enter it

Click Start > Settings > Update & security > Activation > Change the product key then enter the new product key then click Next to Activate
