I'm pretty sure I have the pagefile disabled; both C and D are NVMe drives, and D is raid0. I disabled superfetch a few minutes ago, rebooted, and don't see any performance impact, but the used memory when idle is now 10GB, vs the 19 in that screenshot. No other changes.
I could see the appeal if I was using a platter drive for my programs or frequent data, but it's not 2008 anymore. I'd rather see actual usage over 'the computer knows best'.
