First ever post!!
I have the same problem of Maintenance in progress whenever my laptop is idle. I do not have the KB5015807 installed but I do have it's preview KB5014666 installed as of 2nd July. Event ID 800 is written to Application and Services Logs-Microsoft-windows-Task Scheduler in pairs. Maintenance state changed to 3 when in progress, changed to 1 when not in progress. Prior to 2nd July I see 6 or 7 pairs per day. After 2nd July install of KB5014666 I see many more pairs - dozens per day.
There are also 3 warning entries in the same log at the time of the install referring to .NET tasks requesting wakeup, but Task scheduler shows these tasks as DISABLED, but last run on the 2nd July. My speculation is that Maintenance is in progress waiting for these tasks to run and turn off the wakeup request but the tasks are disabled so will not run. I cannot tell what the tasks are doing as the action is 'Custom Handler'

Welcome to TenForums.

It's really worth making time to browse through the Tutorial index - there's a shortcut to it at the top of every page.

- At the foot of the Tutorial index is a shortcut to download it as a spreadsheet.
- I download a new copy each month.
- By downloading it as a spreadsheet I can benefit from Excel's excellent filtering capabilities when I search for topics of interest.

- Tutorials are also listed by category at Tutorials - there's also a shortcut to that at the top of every page.
- Both tutorial lists are searchable.
- You can also search for TenForumsTutorials in many general search engines, such as Google, by adding site:tenforums.com/tutorials after your search term. For example,
taskbar toolbars site:tenforums.com/tutorials

You can search TenForums using the search box in the top-right corner of all TenForums webpages or using Advanced Search - TenForums
- You can also search TenForums threads in many general search engines, such as Google, by adding site:tenforums.com after your search term. For example,
Search for drivers by HardwareID site:tenforums.com
- [This is what the search box in the top-right corner of TenForums webpages does automatically]

All the best,
Denis

Interesting, I skipped this preview update and maintenance appears to complete succesfully. Not that this should matter much because official cumulatives inherit all changes of previews, unless the cumulative undoes some.

Yeah, pretty much exactly what I'm seeing too, and for the extra bit of info the .NET error in Event Viewer is;

Maintenance Task "NT TASK\Microsoft\Windows.NET Framework.NET Framework NGEN v4.0.30319 64 Critical" requests computer wakeup during next regular maintenance run.

The event id 800 and those three warnings are not new, the warnings have reappeared with every cumulative update since at least march. But who's to say if the disabled state of these .NET tasks is new, or the cause of this bug. They might still show recent runs despite their current state being disabled.

It seems however that the number of these id 800 events has at least doubled since this update. I left the computer idle for about 45 minutes and when I came back, the last state of automatic maintenance as reported by security & maintenance was "last run (the exact time I returned)". I looked at the event logs and saw that apparently the maintenance task had run for about 25 minutes and then it had stopped by itself. Afterwards during shorter breaks it had started again as if it could never finish what it had started before. If indeed there's a problem preventing automatic maintenance from finishing, no matter what the maintenance & security app reports, it could eventually eat away at performance depending on how critical the tasks are. The list of stock Windows 10 maintenance tasks is long already, and some of them are esoteric.

This 'appears' to address the same problem and it is from July this year. I have added my comment.

Looks like this update broke automatic maintenance, it will now never complete.

Normally, maintenance completes before power management suspends your PC; if maintenance completes when scheduled, it will not automatically run again until the next scheduled run. If it is interrupted, however, it will restart the next time your PC is idle.

With this update, now no matter how long you leave the system idle, automatic maintenance never completes, it's always in progress...

This will probably cause performance issues.

I have not installed this optional comulative, but since I installed the KB5016616 update I have the same problem, maintenance is never completed!
