I normally don't have notepad.exe or the windows media player open, so it's irrelevant. Chrome, clangd, rustc, etc. are all that matter. Optimizing anything else fails the pareto principle. I definitely do not want Microsoft paying its engineers to optimize windows media player memory usage.
I don’t want a trillion dollar investment in ram reduction, but the fist 80% of optimisation will be trivially achieved. Microsoft have a conflict of interest given they also sell surface devices where pushing people to the more expensive models is beneficial, while also probably benefiting when other hardware manufacturers benefit too.
