Windows 10: How Do I Specify Windows Update Repair Source in Registry?

Good morning and Happy New Year!

Within my organization's environment, we have a small number of machines that occasionally fail to install updates as a result of missing assembly files (error code: 0x80073701). When this occurs, the Windows Update agent - in some cases, but not all - will attempt a repair (still unclear as to why this inconsistency exists). When attempting repair, it tries to locate a repair source in order to run a process that appears similar to DISM /online /cleanup-image /restorehealth. However, because the repair source is currently not configured in our environment, it attempts to use Microsoft's Windows Update servers by default. Our firewall is not set to allow this and so the process reports that it is unable to resolve the repair source.

Now, I am aware that this can be configured using Group Policy (Computer Configuration -> Administrative Templates -> System -> Specify Settings for optional component...). However, I am curious as to whether or not this can also be configured in the registry?

Additionally, I have a related question: When using a WIM file as a repair source, must that WIM first be mounted? I think that it has to, but wanted to verify as the last time I ran DISM's restorehealth feature, I pointed it to an unmounted WIM file. The process completed successfully but didn't appear to repair anything.

Thank you!

:)

 

Error: 0x800f081f, "The source files could not be found." after performing DISM command

I've run DISM /Online /Cleanup-Image /RestoreHealth with the following results:

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 information on specifying a source location, see

When I go to the suggested link
http://go.microsoft.com/fwlink/?LinkId=243077 this what I see:

Choose a Repair Source

You can use Windows Update to provide the files that are required to restore a Windows feature or repair a corrupted operating system. You can also configure Group Policy to gather the required files from a network location. Multiple source locations can
be specified in the Group Policy.

To use Windows Update to restore optional features and repair Windows images

•Windows Update will be used by default if it is allowed by the policy settings on the computer.

•If you want to use Windows Update as a primary or backup source for files that are used to restore optional features or repair Windows images, you should make sure that your firewall is configured to allow access to Windows Update.

It really doesn't tell you how to designate a repairs source. How do you do that?

Drag and drop to Firefox web browser upload function broke after Windows 10 upgrade (Edge does not work either)

Thanks for the info. I received this error after running "dism /online /cleanup-image /restorehealth"
and it reached 100%. Now some items are missing from my start menu and the task bar search is not functioning, could have other issues now too. Any idea on why I get this error?

I found this info which states that Windows Update is the source used by default unless the specify a different source. I have verified that Windows Update is functioning properly.

Hi wkizzlejr,

That error code is an identifier that a "building block", for want of a better description, is missing/corrupt within a PREVIOUS update that the current update needs to access, and becaue of this the new update fails.
Allthough W10 is a new system parts of previous OS's have been carried over; the Update process is one of them.
Within an update, there are Packages and inside of these are even more sublayers
KB123456 > Packages > Cat/Mum
Thats not all tho
All updates migrate thru CBS and CSI, and within the CSI operation even more pre-update processing takes pace, and
inside these
Components > Payload
Your problem will be within
Cat/Mum/Components or Payload.

The CBS log should point towards the problematic Update and the errors within it.
(not sure if the DISM log does, the old SURT did, and could be fixed using it)

Post the logs.

As for the restore health command was the latter
/Source:wim:E:\sources\install.wim:1 /limitaccess
Where wim:E is the repair source, DVD/USB/ISO from another GOOD machine

MS ITPro - DISM tutorial

Add or Remove Packages Offline Using DISM
Not sure if the term package in this scenario actually relates to a Windows update package.

I do know of another tool that will identify and can insert/replace the missing/corrupt entries,
BUT as your running behind a Server with GPO restrictions!!!,

If all the affected machines have IDENTICAL errors that would infer that this group of received a Bad server patch, or that their GPO's are slightly different from the unaffected machines.

Good morning, and Happy New year @wkizzlejr

Yes the image (ISO) should be mounted first, with the mount command or opened with Explorer (both right-click context options). System will assign drive letter. Example command line here. Sub the mounted drive letter for "G".

DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:G:\sources\Install.wim:1 /LimitAccess
