Windows 10: Service Host open too much taking all my RAM

My ram has been at super high usage and crashing other programs. After looking into task manager the main issue seems to be system host is open over 50 times taking an average of 100mbs.

Browser /connection security, hosts file and DNS service

You're saying that Open DNS(and other services like it) house their own list of known 'bad' sites, and by using their DNS servers, it will filter out sites based on that list?

Would you believe I was already using Open DNS servers.
This means the hosts file is moot?

And furthering that, if there's any bespoke sites I want to manually add, I could do it through my router directly.

Thus I can empty my local hosts file and turn my DNS service back on?

 

High RAM usage (up to 96% !) "Service Host" and "System"

i have installed Windows 10 Pro, it was working normally, but idk how it changed suddenly and became taking RAM highly

main RAM takers:

Service Host: Local System

Service Host: Local Service

System

when i close any (except System) RAM gets empty fast (from +90% to ~20%)

and when System takes RAM highly, i cant do anything, i immediately restart pc

these processes keep taking RAM ascending

1. i tried to run:

sfc /scannow

it found errors but cant fix and here is the
LOG file



2. cleen boot didnt change anything (turn off all non-microsoft services)
