Windows 10: I'm getting 70-90% RAM Usage on newly installed Windows10

As the title says, I just installed Windows 10 yesterday and left it to update. Now it is forcing my app to close because it is using too much ram. What do I do with this? Thanks.
I have 8gb RAM, installed the latest Windows 10 Pro 1904

Windows RAM usage actual and Task Manager not matching.

Hi,

I am using Windows 10 right now and I had used 8 and 8.1 too on my laptop having a 4GB RAM. Whenever I the task manager and check the memory usage, it shows less than 30% of the 4GB ram I had. But still, it shows 70-90% always. Even I had checked
the tab of Users, there is only one user and the total memory usage was around 700 - 900 MB, but the percentage above was showing 70-90%.

When I close almost all applications, the RAM usage was like this:



175 MB out of 3.88 GB usable RAM -> 50% ?

Why is this happening?

Is there anything I could do to avoid this and get my laptop back to normal?

 

90% RAM usage while nothing is open


I just upgraded from windows 7 and I haven't installed any extra programs and I have done a full virus scan with Malwarebytes however windows 10 sits on 90% RAM usage allot of the time, can someone help me please??!

High ram usage.

Hi. For some reason,90% of my ram is being used when idle. I don't know why it is like this. Usually it is at 20% at idle but now it is at 90% usage. The System hosts seem to be using the most ram. Is there any way I can fix this.
