Windows 10: 20H2 hosed my system

This is my wife's computer that I am trying to fix. She works in education and needs her system back. So far ASUS and MS are not a real big help. I cannot go back to the previous windows because we left on a 1 week trip to visit our new grand daughter and come back to a total mess.

• After the update to 20h2 my Asus T200TAC has lost it's sound devices and windows cannot find any sound devices. In the Device manager there is no Sound and Game Controllers selection.
  
• The Keyboard is stuck with a num lock on and I cannot find how to disable it. It is a small keyboard so the letters turn to numbers on the Right side. This makes it impossible to log in without a separate keyboard.
  
• I had to bring out my Logitec USB keyboard to log in the system because the Dock/Keyboard is not usable. I have had no luck with driver updates.
  
• Tablet mode is not working either. When undocked, the touch screen is not functional.

Are you able to follow them?

Update 20h2

Hi Wicki,

I am Sumit, an Independent Advisor and a 3 year Windows Insider MVP here to help.

20H2 should not be installed right-away on your device - MS said the rollout is only to a fraction of users and would be labeled as an optional update initially. Are you enrolled in WIP?

You may uninstall 20H2 using the steps below:

20H2 system files corrupted on a clean Windows installation sfc /scannow

Hi,

I have noticed that sfc /scannow corrected system files. I wonder. So I tested again on a clean Windows 10 20H2 installation and run directly after sfc /scannow.

Preparation for testing:

• I used VMware Workstation 16.0.0
• I created a new virtual machine with default Windows 10 profile
• I disabled the Network Adapter, the OS has
  no internet the whole process
• I used the latest official Windows 10 ISO file Win10_20H2_English_x64.iso (md5: e80f6ce987b2bba288469e7379129e12) Build 19042.508
  
• Mounted the ISO in VMware

Installation:

• So I started to install Windows 10
• Install Now, No product key, Windows 10 Home, Language en-us, install on the unformatted 60GB drive etc.
• After reboot, I used "no internet" for local Account, name: admin, no password, disabled all the telemetry trash

After successful start, I started directly cmd.exe with administrator privilegs and run sfc /scannow.

It will found corrupted systems files.





It didn't let me post the log here, so I made a Screenshot.

What is going on here?

I repeated the steps with de_windows_10_business_editions_version_20h2_x64_dvd_ce126f3b.iso (md5: 35df62707e53c2064641ccd5b91acb8d)

After repeating the steps above, the result is the same.
