Windows 10: High CPU usage: Service Host: DCOM Server Process Launcher

So for quite a while now, I have been having issues with my pc.
After using it for a couple of hours (playing games, browsing the internet, using it for university work, etc.) its performance is noticably lower than just after startup. Task Manager tells me that

svchost.exe Service Host: DCOM Server Process Launcher

is using about 25% of my CPU and 30% of my RAM. This seems incredibly high to me. Restarts solve the issue but I would rather not have to of course.
I've googled the problem already, but a lot of forum posts are from people using Windows 7 or are unsolved.
Standard Microsoft procedure has you using RAM checkers and all that. I did that, and the results were that my RAM is fine.
It is also not Windows update sharing as some suggest as I have that turned off.
I'm really hoping someone can help me here.

After installing the windows 10 update KB3201845, my computer stopped working.

A lot programs including, but not limited to, Chrome, Edge, Settings, cannot be opened. The process "Service Host: DCOM Server Process Launcher" keep using high CPU percentage.

Even I uninstalled the update, the problem is still there. What should I do?

 

Windows 10 auto update broke computer

Hi, I left my computer for dinner today and it decided to install updates and rebooted without my consent.

Anyway, now it is broken:

1. I can login, but then CPU usage goes high and almost nothing works. For example, Chrome hangs; Start bar wont launch processes; etc

2. Task manager will start and shows continuous high CPU from "Services Host: DCOM Server Process Launcher"

3. Running some things using Win-R works, eg explorer, cmd prompt.

I tried a system restore from the system boot but it did not fix the problem.

Please help.
