Windows 10: nearly 10GB of RAM in use all of the time. Help please!

Hello everyone,

I have been reading these forums for a good year but just right now I decided to register as I have quite a big problem.
So 1st things 1st. I have been putting my hard earned cash aside for over a year and finally around a month ago I have bought a new gaming PC.
Here are my specs:
Windows 10 Pro 64bit
GTX 1070 8GB
i7 6700K 4.0Ghz
16GB DDR4 RAM

So I've upgraded my Windows 7 to Windows 10 around 11 days ago and I noticed that for some reason my PC has issues with running games smoothly now. Today I decided to finally find the culprit and to my surprise I noticed that my PC is constantly using up nearly 10GB of RAM, going over said 10GB at times! All while simply browsing the net or simply listening to music on Foobar. It was staying at around 2.5GB on Windows 7 so I don't find this behavior as normal at all.

Here are the Task Manager and Resource Manager readings:

I really do want to resolve it as it seems abnormal and it literally makes the newest games (WWE 2K18, Middle Earth: Shadow of War etc.) unplayable, whereas they worked perfectly fine under Windows 7 which wasn't using such a ridiculous amount of my RAM.
Thank you in advance for all the provided help.

Is your Windows install fully up to date? Also, after upgrading to Win 10, did you install the latest video drivers (from Nvidia)?

Look at the processes what do you have like 50 running?

Agreed. Seems there is a lot of Chrome going on there...

I partially fixed it by noticing that after the upgrade the paging file of my Windows drive set itself to manual for whatever reason. I switched it to auto and it seems to be stuck at around 4GB of ram usage now, which is still too much in my opinion.
I'm really lost. As for Chrome I simply had around 8 tabs opened as I was searching for the solution for my problem. It was around 10GB even with Chrome completely turned off.

I noticed that there's a TON of things called "Service Host" running in the background, in fact, something around 20 of them? Most doesn't even make sense, and every single one takes a good 30-40mb of RAM all of the time.

I'm honestly lost. I do know for a fact that Chrome uses up a lot of RAM, but now, after sorting out the paging file, it's still going as highas 5GB on idle... when simply running Foobar for music and Avast in the background.

My drivers are up to date.
