Windows 10: Is it normal for SysMain to randomly spike up to 20% CPU usage?

Every so often, SysMain's CPU usage spikes up to usually between 10% and 20%. I only just caught wind of this and I'm not too sure if this should be happening. I noticed it happens a lot when I'm playing games like Minecraft Java Edition, enclosed is a screenshot.I have heard some people say to turn it off but I'm not sure I should since I'm only using a HDD.Is this normal behaviour for SysMain in a HDD?

Audiodg.exe Spikes Cpu Usage

Every 5 minutes or so audiodg.exe spikes my cpu usage to about 50% and any audio im playing cuts out and then comes back a second or 2 later. The video is completely fine and it's not a problem with
my USB Headset. audiodg.exe stays at low cpu usage when it's not spiking.

Solutions I've tried:

1. turning off audio enhancements
2. reinstalling lan, and audio drivers
3. turning off HPET
4. lowering the sound quality in control panel
5. DPC Latency checker (no change when spiking)

None of these solutions work. Please help.

 

Spikes in CPU usage

Open Task Manager and under list of Processors , sort them by CPU usage and see what process is using it.

1% to 17% is normal and it might be background task for maintain Windows or Anti-Malware check.

Does it happening with Rainmeter skin?

 

Explorer constantly spiking CPU usage for Win 10

Hi. Thank you for your answer. I tried all your suggestions, but nothing helped.

Clean bot seems helped at first but no after some hours spikes came back and now spiking more often with every hour of PC working.

Same happened also without clean boot.

Any other suggestions what to try ?

Just to let you know that I worked with Win 7 before with even more programs installed than now and I did not switched off my PC for weeks and CPU usage was lower in general not to talk about any spikes in CPU, newer noticed anything like that...

Thanks
