Windows 10: Window Enterprise, how do I uninstall, and install new Windows 10????

Last year I had an "expert" do work on my laptop that was in need of more memory, and a general clean up. It was running Windows 10 which was the free upgrade from Windows 8. Unknown to me, he completely uninstalled my legal software, and installed a copy of Windows Enterprise. I didn't even know it was Enterprise until I got the "activate your license" message. I purchased a new copy of Windows 10 from Microsoft store, but Enterprise wont let go of computer, I tried to install from usb drive, but still have Enterprise showing it is OS. I am unhappy that this guy possibly installed somewhat illegal Windows, I just want to get it off my laptop.

Any help for me???

Installing Windows 10 on New PC?

I'm going to be building a new PC on Christmas and want to install Windows 10 on it. I have Windows 10 on my current PC, which I installed upgrading from 8.1 with the files on a USB. How do I go about installing a clean copy of Windows 10 on this new PC? I think I recall something about installing it once makes Microsoft recognize your hardware, but since this will be a PC I'm not sure what steps I need to take. Do I need to go 8.1 -> 10 or is there a method of going directly to 10?
