Hello, I recently built a gaming pc. I bought a usb stick and key on eBay. Windows 10 installed fine but a when I tried to install netframework 3.5/4.5 or whatever its called and it wouldn’t. I ran the trouble shooter but nothing came up. Also I tried to update to windows 10 1803 but I wouldn’t up date I ran the trouble shooter I found an error and I fixed it but it wont update still.
