My Windows 10 Version 20H2 will not install the update 0x80004005.

I downloaded Windows 10 update tonight on two computers KB5001931 and they both worked

  Microsoft finally fixed the problem.  I have trying to update KB5001831, not sure of number and it failed each time.

I have the exact same problem. Have you had enny luck yet? I really don't want to do a complete win1p installation.

Hello Howard,

Here's a suggestion,  I forgot to mention that previous to doing the final windows 10 installation I opened device manager first and went through every entry and updated each listed driver, some updated automatically through Windows but most had best driver installed, apparently an incompatible driver can cause an installation problem with 20H2.  Maybe worth a try to update your drivers.

I have done almost exactly the same things you have done with the same outcome every time. Totally frustrating. I have read that even some folks that have bought brand new PC's still have the same issues. Unless Microsoft comes up with a solution and I doubt they will, I am guessing I will be running 1909 till me or my PC dies. :(

I’m having the same problem, but the problems I’m having is 20h2 the updates are not automatically updating and I’ve got no sound I don’t get what’s doing this because I’ve downgraded to 1909 and it automatically updates windows updates there is no problem with the sound so if I do a fresh clean install of windows 20h2 then there’s no sound on the volume icon it’s got a red circle with a white cross and you have to go into optional updates to do it manually then when you tick the box you download what’s in the list of updates then you will see the screen flicker and then I will have sound but you have to do this manually is anyone else having the same problem because I’m going out of my head here I’ve google it trying to find what could be causing this I can’t find nothing.
