For the past few months, Microsoft's cumulative update changelogs have not provided detailed information on what was fixed.

Microsoft states that the only non-security fix in the KB5010386 update is for an LDAP issue, causing operations to fail.

"Addresses an issue that causes a Lightweight Directory Access Protocol (LDAP) modify operation to fail if the operation contains the SamAccountName and UserAccountControl attributes," explains the KB5010386 update release notes.

"The error message is, “Error: 0x20EF. The directory service encountered an unknown failure”.

Last week, Microsoft released a Windows 11 preview update that resolved Windows 11 File Explorer performance issues when switching between, browsing, or selecting files. Even though Microsoft did not list it in the changelog, these fixes are also included with today's Windows 11 cumulative update.

Otherwise, Microsoft states that there are no know issues with this update.

Finally, Microsoft updated the servicing stack to resolve bugs or issues preventing Windows Updates from properly installing future updates.
