Windows updates failing with the error code 0x800703f1

[Golgo 13]

Hi Sysnative Team!

I've been struggling with this issue for a few weeks now, I feel like I have tried every fix on the internet but these updates are still failing to install. The updates usually fail after a few minutes once the install process has started.

This is a VM running Server 2019 Standard. It has Remote Desktop Session Host roles installed.

SFC Scan​

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files but was unable to fix some of them.
For online repairs, details are included in the CBS log file located at
windir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log. For offline
repairs, details are included in the log file provided by the /OFFLOGFILE flag.


Log File CBS Zip is attached.

Hi and welcome to Sysnative,

Here's the first fix, it's too lare to attach so I've uploaded it here: SFCFix.zip

Step 1. Download

SFCFix and save it to your desktop.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

• Save any work you have open, and close all programs.
• Download the attachment SFCFix.zip and save it to your desktop.
• Drag the SFCFix.zip file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth

Thanks Maxstar!

Unfortunately the DISM command failed at 80.3 percent.

I have attached the new CBS Log folder

Can you please check if you have another server for the following component folder? If so please provide a copy of it, otherwise I'll need to rebuild a Server 2019 VM for the last file

C:\Windows\WinSxS\amd64_microsoft-windows-dynamic-image_31bf3856ad364e35_10.0.17763.737_none_b516408bbaf46523\WindowsDefenderApplicationGuard.wim

Hi Maxstar.

Thank you! This last fix actually allowed the DISM command to get to 100 percent.

I downloaded the updates and tried again, They didn't fail this time but the system was stuck on "Restarting" for over 12 hours while trying to install the updates. I ended up having to force a reset.

I haven't tried installing the updates again but I will give it another go tonight.

Hi,

Sometimes it may take some time to complete especially when the update process performs a cleanup task during the last reboot.
