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!
