Hello guys. Just bought a new prebuilt PC from Illegear with non-activated Win10. Then I bought the cheap shopee win10 activation key, but I can't activate them because Microsoft think I'm trying to reactivate Windows10 from my old Lenovo laptop tied to my Microsoft account, on this new pc. So I got the hardware change error, tried to use the troubleshoot and Microsoft said the problem is because windows edition dont match with the old laptop tied to the account (Win10Core single language). Any idea how to proceed from here? Any setting to say its a fresh install on a different PC or to remove the old laptop from being tied to my account or something?

Windows 10 Settings > Activation > Change Product Key

Done

Already did this but got error. Maybe I got a bad key. In contact with the seller right now.
