I am currently on Windows 10 Version 22H2 (OS Build 19045.7417) Last month, I was having problems with the July cumulative update and got the same persistent 0x8007000d error.

Last month I tried the following:

I tried running the Windows update troubleshooter.

When that didn't work I ran DISM /Online /Cleanup-Image /RestoreHealth and then restarted and did an SFC scan.

When that didn't work, I tried clearing my download cache.

After that, I was still hitting the same error. By the time I had noticed I was missing an update, it was late enough that I figured I should just wait for the next cumulative update, but this month's update is also returning the same error. It is the exact same error as last month: "Some update files are missing or have problems. We'll try to download the update again later. Error code: (0x8007000d)" This is happening after the installation reaches 100%

The cbs file is very large (around 42 MB) after I attempt to download the update, so I can't attach the full thing, but I can search through it and paste anything relevant if I know what to look for

Before I try an in-place install, I would like to know if there are any other, less invasive steps I can take. In addition, if possible, I would also like to diagnose the problem specifically, if just for my own curiosity and peace of mind.

Please do a repair installation using the Media Creation Tool.

Your apps, settings, and files will be kept by default during a repair install/in-place upgrade.

    Hi Jasmine,

    Thank you for providing the details of the troubleshooting you've already completed. Since the same 0x8007000d error is occurring across multiple monthly cumulative updates, it suggests Windows may be encountering an issue with update data or servicing components rather than with a single update package. Based on your description, you've already covered many of the standard repair steps, including the Windows Update Troubleshooter, DISM, SFC, and clearing the update cache.

    Before moving to an in-place repair upgrade, you may consider manually installing KB5120249 from the Microsoft Update Catalog. If the standalone installer produces a different error or fails at a specific stage, that information can help narrow down the cause.

    If the manual installation produces the same result and the logs do not reveal a specific component that can be repaired, an in-place repair upgrade would be a reasonable next step.

    I hope this helps point you in the right direction. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
