This has been going on since May. I've tried many of the suggested solutions to fixing the "failed to update undoing changes", but none have worked so far. I will list the steps I remember trying: disabling bits, deleting the update files in safe mode, deleting them not in safe mode, deleting MS edge files, running DISM, chkdsk, running the troubleshoot, running update assistant, enabling .NET frameworks, disabling firewall, disabling my AV, stopping the update service, enabling update & repair on secondary apps (i think its how its called), etc. Windows also gave me error code 0x800f0922 today
