Computer runs hot every 5 minutes when idle, WHY!?!

My laptop has been a constant victim of these godforsaken programs that run every 5 minutes when idle, and it's starting to make me angry.

It's either the Windows Modules Installer Worker, or Service Host: Disk Defragmenter, or System And Compressed Memory. One or the other acts up around every 5 minutes when idle. It's been going on for over a year now, and I believe it's reducing it's lifespan because the fan speed increases and the laptop becomes hot to the touch. What the hell are these programs, and what can I do to stop them? I am willing to do anything at this point to prevent them from running. I'm worried that the fan is going to blow out if this keeps up. Please, somebody help. If you need any info at all, please let me know and I will give it to you.

Hi, from my notes on System and Compressed Memory, noting you're using Chrome, try

Solved High CPU usage - System and Compressed Memory - Page 3 - Windows 10 Forums

It’s solved now. Just disable the desktop notification in Chrome.
To do this you just need to launch Chrome, go the the address bar and type "chrome://flags" and then search (ctrl+F) for "#disable-accelerated-video-decode". By default this should be "off" but if you turn it "on" you disable it (you turn on "DISABLE" so that's why "on means off").

Is this normal? System and compressed memory process ALWAYS at 20% cpu

Wrightclick: #10 I started killing processes one by one and discovered the process 'speech runtime executable' to be the culprit. When I killed it, CPU usage for 'system and compressed memory' went to zero.

However, after killing the 'speech runtime executable' I could no longer talk to Cortana (Hey Cortana). Oh well. At least I got my system back.
All I have to do is click the 'O' in Quick Launch on the Task Bar and then type or just click the Mic in the bottom right corner to talk to Cortana. Works fine. But after you talk to her that 'speech runtime executable' process shows up again and the 'system and compressed memory' process is pegged back at 19% CPU again.
Once you kill the 'speech runtime executable' process, the CPU usage for the 'system and compressed memory' process goes back to zero.

- which is not a solution, but worth an experiment.

Likewise, try this:
Turn off "Get tips ..." in notifications in Settings->System->Notification&actions.

Do you have these issues in
a. Safe Mode
b. after a clean boot?

Thanks for your response, I will look into those and see if there is anything that can help. I do use Google Chrome, but I don't think it's related at all. It feels like a Windows thing, more than anything.
