Unknown Background Processes

Microsoft Engineering with recent updates(1709+) has broken Some process like Service host to many in order to make performance better. So what you are seeing is normal.

Thank you, that's good to know.

I've looked up the processes I didn't know. According to some Google results the first one called WMI Provider host allows applications to request informations about my system. That's already weird because I haven't ever seen it until I installed that update. Since I didn't install any new applications, I guess none of my current apllications really need it. It usually doesn't really use anything but sometimes it spikes to up to 25% CPU which makes it noticable while doing stuff like gaming. Some sources say it's important, others say you can disable it without any problems.

Windows Shell Experience Host*is realted to built-in apps.*It's usually not a problem but it does like to use some RAM. I haven't ever frequently seen it in the Task Manager before that update either.

Windows host process (Rundll32) *is used to run the functionality of dll files.*I get why it has to run for certain applications but it still freaks me out because it just turned up without installing any new applications.

The security and monitor stuff seems to be related to Windows Defender (even though that's not running at the moment). The applications of these processes are located in System32, so I guess they're Windows OS stuff. It's still kind a annoying though, that they're using quite a bit of CPU and RAM sometimes. Considering they never ran on startup before that update (maybe some of them were running sometimes but not on startup) makes them a little suspicious. Any idea what makes them behave like that?

My specs should be fine. I've got an i7 8700K and 16 GB of RAM. Windows is installed on a Samsung 960 Evo NVMe SSD.

I'm gonna check out the other steps as soon as I can. Thanks for your answer.

Hi Phillipp. I'm Greg, an installation specialist and 9 year Windows MVP, here to help you.

Those are normal as far as I can see. Do you have 4 or more GB Ram? I have noticed the difference between 4 and 8gb on Windows 10 with a capable core i-3 or faster processor can make a difference in performance. So you can check your present configuration and expansion options by running the excellent Crucial System Scanner which is the ultimate authority on RAM spec'ing, configuration and updating: http://www.crucial.com/systemscanner/

In Windows 10 we have found that what matters most is the quality of the install. Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files. Then continue with the other steps to go over your install most thoroughly.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
