Windows 11 24H2 Updates Download Failure (Error 0x800b0004) due to UUP PSF Metadata issue

Hey everyone! English isn't my first language so I’m using a translator. Sorry if anything sounds a bit off—hope you can still understand me!

Issue Summary: > I am encountering Error 0x800b0004 when downloading Windows 11 24H2 updates in MECM. The error specifically occurs on .psf files.

Details:

The issue is documented in Microsoft’s "UUP FAQs" (Point 5), stating that upgrading MECM does not fix metadata synced prior to version 2111.

PatchDownloader.log shows: "ERROR: DownloadUpdateContent() failed with error 0x800b0004".

Temporary Fix: Manually updating the CI_Files table(SQL) (setting IsSigned=0 where FileName like '.psf') allows the download to proceed, but this is required every month for new patches.

Request: I need an official fix or script to resolve the corrupted UUP metadata in the database once and for all, as re-syncing the "Windows 11" product does not clear the invalid records.

    The error code 0x800b0004 you are encountering during the download of Windows 11 24H2 updates in MECM is related to issues with the UUP PSF metadata. This specific error indicates that there is a problem with the metadata for the .psf files, which is preventing the updates from being downloaded successfully.

    As a temporary workaround, you have already found that manually updating the CI_Files table to set IsSigned=0 for files with the .psf extension allows the download to proceed. However, since this needs to be done every month for new patches, a more permanent solution is necessary.

    Currently, there is no official fix or script provided by Microsoft to resolve the corrupted UUP metadata in the database permanently. Resyncing the "Windows 11" product has not cleared the invalid records as you mentioned. It is advisable to keep an eye on updates from Microsoft regarding this issue, as they may release a patch or guidance in the future that addresses the UUP metadata problem more comprehensively.

    In the meantime, consider reaching out to Microsoft support or checking their forums for any updates or community-driven solutions that may help resolve this issue more effectively.
