Windows 10 Pro Updates

[WGM53]

I dont know what the issue is with windows updates. I built a new Asus PC 1 year ago on the 390 platform the  Maximus XI extreme . I installed windows 1909 at the time and updates and running were fine.

When 2004 came out the system wouldn't update. Just waste my time and on last reboot would roll back changes. Everytime I tried it would give a different error code. An IT friend gave several suggestions 

but nothing worked. Now I'm dealing with same issue on 20H2. Every attempt just rolls back. Unplugged USB devices, Unmapped my other PC's (Which have updated Successfully) and lastly used Microsoft

Media 20H2, which was a failure also. Used all the best name parts, Asus, Samsung M.2 NVME 2t ssd,1200 Watt corsair PS, and 240 Corsair AIO cooler. My Intel I9-9900KS runs around 47 Deg at idle and

2 cores may hit 100 running Sinebench. Have it overclocked at 5.1 and has never froze or locked up. Am to the point of completly tearing it apart, selling the board and CPU and starting over. Any idea's

Thanks,
