Everyone knows OS and software, browsers, etc all use way more RAM than they used to, and arguably more than they rightfully should. Bloatware, etc.
I saw something recently that alleged MS puts a lot of shit into PCs that say they are doing one thing but are really doing another.
It would be wild if they are basically using the PCs of the world to do something like crunch numbers, mine bitcoin, etc. Oh, hey, this guy has 12 gigs of ram and is only "using" 4, that's 8 for us to sap.
If only they were that competent. Shit is slow and uses lots of ram because everything is a chrome browser now. The start menu is react. The notifications popup is an electron app. Any time they draw a box on the screen they're loading another instance of a full browser.
