windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

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.

 

Usable Product Keys for Enterprise downgrade to Pro


Hello wetenhr, and welcome to Ten Forums.

You could downgrade to Windows 10 Pro using the generic key under step 1. You'll still be using the same version that you currently have installed, but you will be able to update to the latest version and build via Windows Update.

When it's finished downgrading, you could try to activate Windows 10 Pro with your Windows 7 Pro or Ultimate key. If unsuccessful, you may need to purchase a Windows 10 Pro key from the Store to use to activate with.
