I recently bought a used dell xps 12 1st gen with windows 8 on it. I wanted to upgrade to windows 8.1 but they asked me first to update my windows 8...so it said 111 updates were available to download...i downloaded, and when I rebooted the windows configuration went up to 15% then said windows update failure, reverting changes. And this never ended so I had to freaking reformat.
How the hell do I fix this
