On Windows 10? I closed everything except Firefox (and this HN tab), which is taking up 600MB of RAM, and now it's at 4.6GB of RAM. Before with two instances of GoLand, Slack and Discord open it was over at 8GB of RAM.
On a Windows 10 VM set to 2 GB of RAM, Windows idles at about 1.1 GB.
On a 16 GB Windows it uses about 7.5 GB. All of that seems to swap out or go away somewhere if I get busy with Visual Studio.
On a 64 GB Windows it seems to idle at about 9.6 GB used. Of course, this one isn't a purely work machine and has Steam, Origin, Ubisoft's thing, etc, etc.
So Windows 10 is pretty variable. I imagine it has something to do with running various services in parallel.
What quantity are you measuring that's 7.5 GB... and what else do you have on that machine? I quit Chrome on my current machine which has a bunch of other stuff and has no less RAM than yours, and even then I was left with <4GB of anything I could regard as usage. It can't possibly be just Windows itself idling at 7.5 GB?
Except my system has 16GB and it idles at 4GB. My old system with 8GB idles at 4GB even my system at home with 16GB idles at 4GB. I dont understand why it would idle at 8GB.
