Take a close look at Task Manager and what all is being launched at startup.
The more being run the more likely there will some conflict or bug consuming and not releasing RAM.
Simplify by disabling identifiable apps, services, and processes being launched at startup.
Research any apps etc. that you do not recognize - could be some corrupt, buggy, or poorly designed software has slipped in.
It also appears that you are running multiple AV apps. Likely counterproductive.
Resource Monitor and Process Explorer may also help identify some specific cause(s).
Once you have the system "simplified" then you can begin adding apps back one at a time (if desired) and determine if the RAM problem reoccurs with respect to some particular app. Or combination of apps.
You must be methodical and careful. Things may appear okay at first but the problem may not reappear until after a restart. Change only one thing at a time and keep notes so you can reverse a change that did not help or made things worse.
Well I need a little more help than that, that's why I made this post in the first place and added the screenshots, I can not distinguish any "weird" apps or apps that should not run and the ones I dont know what exactly they do they seem to be system/windows apps. So could you give some insight on where to start?
As restarts this is the memory usage of every restart. My starting apps are the ones seen on my first screenshot except viber (which I usually manually start after a restart at some point)
So bitdefender,Intel GPU control panel thingy, Intel rapid storage technology, BT devices, windows security and Steam.
As for multiple AVs I think you mean antiviruses? I only run the bitdefender suit oh and the build in windows security
As for the resource manager I will post a screenshot to my reply to
@Colif so that I post it only once.
What are specs of the PC? What motherboard do you have?
Likely you have a driver memory leak.
What is showing as using most ram in Resource monitor? (to access it, go to Task manager/performance and click link at bottom of page). Go to the memory tab and sort by private or working set and show the processes using most memory
Private bytes = actual ram usage
Working set = Ram + page file usage
try turning off Fast startup and see if it gives you ram back at startup -

multiple AV? I only see bitdefender running?

As for resmanager this is a screenshot of top consuming ram apps in respect of working set
