Windows 10: Windows 10 1903 Update Fails with 0x08000405

My PC was assembled, and had a fresh copy of Windows 10 installed onto the brand new SSD on 8/29,2018. It is currently running the 1803 (17134.885) build. While I am constantly prompted to update to 1903, I have not been able to do so.


I have tried every posted solution I can find. Every single time, the Automated Update silently fails after reboot, then eventually downloads the Update again, and once more notifies me that I need to update to 1903 before November in order to remain in support.


This has been going on for over a week now. Today I decided to dedicate some time to resolving it. After trying several suggestions skimmed form the web (most of which include some version of deleting or renaming the Software Distribution folder and/or the Catboot2 folder... after stopping the Windows Update Service and the restarting it following the folder delete/rename), I gave the Windows Update Assistant a whirl.


This also fails. Every. Single. Time. But at least I get an Error Code to research. Not that it helped. So, today I've burned a number of hours (hours that I should have spent working) on this problem, and I've reached absolutely no resolution on it.


None of the solutions offered in this thread helped:


https://answers.microsoft.com/en-us/windows/forum/windows_10-update/error-0x80004005-window-10-update-failure/156adfb8-e7e1-46fa-b5c6-cbd5dcfebbb9


So if we could skip repeating those, I'd be appreciative.


In case any of this is useful or pertinent:


My rig is an i7-8086K running at stock 4.00GHz with 64GB (4x16GB) of G.SKILL TridentZ DDR4 3000 RAM all installed on a Gigabyte Z370 Aorus Gaming 7-OP (with the 32GB Optane). Windows is installed on a Crucial MX500 M.2 2280 1TB STA III SSD and my data is stored on a WD Black 4TB HDD. I keep my drivers up to date, but I do keep my PC running 24/7, and sometimes I put off updates for a few days at a time to keep on working. I have not previously had any issues installing or updating Windows.

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

Then if the issue persists, please return to the trouble shooting list in post# 89

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.

 

Windows Updates failed to instal

I just did step one and they have just all installed.... thank you so much.... it was quite frustrating having that update window pop up every 5 minutes and failing to instal every time

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.
