Windows 10: Windows 10 Feature Update 20H2 failing to install.

I am currently running Windows 10 version 1909 and am repeatedly asked to update with Feature Update 20H2. I have tried to update and install dozens of times without success.

I have read everything I can find offering solutions and have tried these fixes also except a clean install of Windows which I want to avoid without any success.

The update literally takes hours and always fails at the last, when final update is at around 90%. My system is then reverted back to it's previous state.

I am now seeing error code 0xc1900101. I have tried all the fixes for this but still cannot update and after each failed attempt, my system settings again repeat the cycle, advising that an update is pending.

I have now found a Log File that lists the errors. This was in C:\$WINDOWS.~BT\Sources\Panther and it shows the following:-

Thanks mate

 

Windows Updates failed to instal

I'm not sure how differant XP media center Edition is but you could clear the history \ cache if these folders are there.

Step 1 Register DLL files.

=================

By trying this step, we can check if the update engines are working properly.



1. Close all instances of Internet Explorer.

2. Click Start and Run, type "Regsvr32 atl.dll" (without quotes) in the Open box and click OK.



Note: There is a space between regsvr32 and atl.dll



3. Similarly, one by one, register the files listed below:



Regsvr32 msxml3.dll

Regsvr32 wuapi.dll

Regsvr32 wuaueng.dll

Regsvr32 wuaueng1.dll

Regsvr32 wups2.dll

Regsvr32 wucltui.dll

Regsvr32 wups.dll

Regsvr32 wuweb.dll

Regsvr32 qmgr.dll

Regsvr32 qmgrprxy.dll

Regsvr32 jscript.dll



Note: If you encounter errors while registering any of these files then skip that file and continue with the next one.



If the issue persists, let's move on to the steps below to verify Windows Update services and temporary folders.



Step 2 Verify the relevant Windows Update services.

=========================================

1. Click Start->Run, type "services.msc" (without quotation marks) in the open box and click OK.

2. Double click the service "Automatic Updates".

3. Click on the Log On tab, please ensure the option "Local System account" is selected and the option "Allow service to interact with desktop" is unchecked.

4. Check if this service has been enabled on the listed Hardware Profile. If not, please click the Enable button to enable it.

5. Click on the tab "General "; make sure the "Startup Type" is "Automatic" or "Manual". Then please click the button "Stop" under "Service Status" to stop the service.

6. Then please click the button "Start" under "Service Status" to start the service.

7. Please repeat the above steps with the other services:



Background Intelligent Transfer Service

Event Log

Remote Procedure Call (RPC)



Note: Event log service is enabled on all of the hardware profiles; this service does not have an option to enable or disable on certain hardware profile.



If it still does not help, let's proceed to step 3.



Step 3 Reload the Update temporary folders.

===================================

One possible cause is that the temporary folder for Windows Update is containing corrupted files. Let's erase all the files there to get the system clean.



1. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net stop WuAuServ



2. Click Start, Run, type: %windir% and press Enter.

3. In the opened folder, rename the folder SoftwareDistribution to Sdold.

4. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net start WuAuServ



Please test the Windows Update website and let me know the result. If the issue persists, to clarify the issue and provide more accurate troubleshooting steps, please assist me in collecting the following information.
