[SOLVED] Windows Server 2012 R2 updates failing to install 0x800f0900

Hello

I have a 2012 R2 failing to install security monthly rollup updates. .NET seems to be fine.

Latest attempted update was KB4503276 with the below from WindowsUpdate.log:

The last successful CU to install was January 2019 (KB4480963).

Trying to run dism /online /cleanup-image /restorehealth /source:<repairsource> /LimitAccess always returns:

Deployment Image Servicing and Management tool
Version: 6.3.9600.17031

Image Version: 6.3.9600.17031

Error: 0x800f081f

The source files could not be found.
Use the "Source" option to specify the location of the files that are required to restore the feature. For more informat

For <repairsource>, I've tried all sorts:

• WIM:E:\sources\install.wim:2 (2 is the correct and matching index)
• \\2012r2server\c$\Windows
• \\2012r2server2\c$\Windows

sfc /scannow suggests it found corruption and it could not resolve. Running SFCFix also said it found some issues and fixed them but not all. Log attached. CBS.log also attached (it's tiny!)

Thank you for any time you can offer!

Interestingly after running SFCFix I had another attempt at running dism /online /cleanup-image /restorehealth /source:WIM:E:\sources\install.wim:2 /LimitAccess and it ran through no issues suggesting it fixed corruption! So I had another go at installing the KB4503276 and it installed!

To me, it seemed like something fundamental was wrong with some core component that only SFCFix could do. Any insight you have would truely be appreciated, to help me flesh out my understanding a little.

Hi!

Unfortunately, From the logs you provided, it looks like there were corrupt system files and SFCFix has managed to fixed them all. Unfortunately, the logs you posted do not contain the list of the files, so I can't tell you exactly what was repaired, but I am very happy to hear that the update installed successfully.
