I tried this process, but it rejected the 'rename' commands, with an error "Access is denied", even though I was running as administrator.

What AV are you running and have you tried uninstalling it?

    im having the same issues with no other AV besides windows defender. A youtube video suggested creating a batch file that didnt yield me the access denied and still fails to fix the issue.

    Only running Microsoft Defender AV, which was enabled, but there were other updates held up by this Cumulative Update 24H2 hanging at 81%, including some Windows Security and Microsoft Defender Definition Updates, and a .NET Framework Quality Update.
    After going through the above steps from UriahZane, despite the 'rename' errors, I finally got the Update to restart, which installed the security and .NET updates that were pending, and then successfully completed the 2025-04 Version 24H2 installation.  So things appear to be resolved and working now.
