Windows 10: Windows 10 Product Key

I am building a new computer New Build. New MOBO, new processor, new everything. I bought a computer from ebay eBay Computer about a year or two ago that has windows 10 pro. I have been researching and found that myslmgr -dli command shows it as a RETAIL version. When I run the command wmic path SoftwareLicensingService get OA3xOriginalProductKey to view my product key it shows as blank which has me worried. I was able to recover what seems to be a legitimate windows 10 product key using a third party software on my eBay Computer but I am afraid to deactivate this key in order to use it on the New Build. Can someone explain any ways to make sure that if I deactivate my windows 10 key which seems legitimate on my eBay Computer that I will be able to reactivate the product key on my New Build? If buying a new product key is the end result thats OK but if I do not have to spend $200 for Windows 10 Pro because I have a legitimate RETAIL key and can re-use then I would like to do that. I do not, however, want to deactivate the product key on the eBay Computer if there is a possibility it will not be able to be re-activated, and I would really just like a way to tell if I am going to be screwing up my product key trying to re-use it before I do it?

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.

  and hit Enter.
