To mr. ed... Your having Windows 10 installed on that PC you had issues with is recorded on Microsoft's servers. With another PC, get the Microsoft Media Creation Tool and create an USB ISO Windows 10 stick. Use this as I mentioned in my earlier post and Windows 10 will be back on your PC and automatically registered to you by Microsoft Servers. You will just need to enter your email address and password that you use in regard to your Microsoft account. If you don't remember same you can easily call Microsoft's Win 10 Tech Support and they will help you out. After you do the install of Win 10 you just have to get your programs reinstalled on the system and get your personal data files back on there also. Not at all hard to get your Win 10 back on there.
