    The actual fix came with the July 7 out-of-band KB5004948 which is also a part of the cumulative update July 13 KB5004238. KB5005010 is an informational document only, nothing there to install.

    The full listing of available update packages is in the Security Updates table in the CVE:

    While KB5005010 is not an actual update file/installer. It is instructions to apply registry entries to further harden systems after applying the July 6th updates.
