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.

 

Brand new sealed USB/key - 0xC004C008 error

I've recently purchased a NOS copy of Windows 10 Pro for a VMS system. This is USB media + product key. It's not the first time I've made a purchase like this...I've made multiple purchases from the same vendor. The product came in the standard package, sealed in cellophane, just like every other copy I've ever bought.

However, in this case, when I try to activate, it tells me the key has already been activated with error code 0xC004C008 . How exactly has this factory sealed key EVER been used? I have to think this is an error with the activation center, and try as I may, I cannot find the correct phone number to speak to an actual agent.

How should I proceed?

 

Clean Windows 10 (?PRO?) install

I have bought a legit "Windows 10 Pro" key of a key website. It is legit since i'm currently using it for over a year now. I currently have Windows 10 Pro installed on my PC and I want to do a clean install. I just can't find the windows 10 Pro download in the tool. But if i could use a windows 10 pro key with a normal windows 10 install, I'll be good to go.
