Windows 10: Windows 10 shows "Activate Windows" prompt even though I have a product key already

Can someone help? I've never had this issue before.

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Windows 10 activation question

do the upgrade
it should activate automatically when online
if you want todo a clean install after that simply boot from your windows 10 installation media and when prompted for a key during install/post install select skip ..
it will re-activate within 5M of being online

 

Windows 10 Activation (Insider)

Yeah they blacklisted the insider keys at RTM, so u need to activate it again. They're using KMS server activation, so there's only handful of keys.

If you don't have any luck I can show another quicker method...lol
