4 minute pause = large cpu increase [SOLVED]

v23.0.66 Still getting MC cpu usage increase when pause goes beyond ~4 minutes  :o

No recording in progress
Just watching a recorded tv show CPU ~10%
Press PAUSE, CPU ~10%
After about 4 minutes of pause, CPU goes to 30-40%
Stays there until press PAUSE to resume, then CPU drops back ~10%

Is anyone looking into this? Usually it's not a big deal, but if I have 5 or more recordings in progress, it could mean MC cpu edging into dangerous territory (affecting recording quality). It's easy for me to stay out of trouble but all the other users not so much.

In the tree on the left, under Services, look at Reporter.  Maybe something else is running.

What are you talking about? Tree? Was this post meant for another thread?

No.  Expand Services on the left side.

I guess you are talking about Task Manager.

No.... In standard view the column on the left is called the Tree. Click on Services there to see what may be running.

The missing piece of information is that the Navigation Tree is in Standard View, and I would bet tzr916 is in Theatre View. In fact, he would be in Display View, since he is watching something and pauses it.

Aside from that, there is definitely a CPU usage increase both in playback since early MC23, and during the pause of video, and it is not related to any activities reported by MC in Reporter.

BTW, a "Sorry Jim I don't understand" may get better responses and attention to the issue than "What are you talking about?"

I have not tried standard mode, only theater view... I did some quick poking around just now:
-I'm running dual monitors so I put Task Manager in the smaller second monitor.
-Play a tv show, press pause, wait 4 minutes.
-Appears the MC process stays the same, but one of the "System" processes jumps way high.
-If I move the mouse or press a button on the remote, that process drops way back down again.

I guess I have to get out Process Explorer to see more details on the "System" that process is somehow monitoring MC being on pause for exactly 4 minutes, as I can reproduce this behavior 100% of the time.

SOLVED

Not a MC issue. Same symptom if I pause WMP for 4 minutes. Process Explorer shows SYSTEM Process (ntoskrnl.exe!kelsattachedprocess+0xf0) was jumping to 24% when either player was on pause for 4 minutes.

FIX: Disable Automatic Maintenance in Windows 10

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\Maintenance

Add DWORD MaintenanceDisabled = 1

https://www.tenforums.com/tutorials/40119-enable-disable-automatic-maintenance-windows-10-a.html

No reboot needed. Effect was immediate. No more worry about pausing video.

Good that you found it, but wouldn't it have been better to just change the settings so that it ran at some safe time, such as 2:00 am, then let it wake the PC (if asleep) to run, and finally let it run once to completion so that it wasn't always trying to catch up (which is why it starts as soon as it can when a video is paused)?

If you leave it turned off you won't get any Windows updates (okay, maybe that is good!), and security scans, system diagnostics. That is a bit of a risk.

From what I have been reading- Regular windows updates will still continue and setting it to run at a specific time does NOT affect the "maintenance while idle" mode.
