Please, when you want to get a new version of your graphics driver or update something too big (say KDE, Mate) you end up replacing the whole OS. You can change window manager, terminal emulator or shell (ksh, zsh) etc. any time, but some fine grained stuff like choosing the version of a program you prefer to run is only possible on Windows as well as e.g. setting targets for fan control, looking for voltage drops - linux never allowed me to read ANY of the half dozen or so voltage sensors built in any PC, it doesn't even acknowledge their presence.
It would be good to have a low footprint Windows clone to do the low level tasks that are just impossible on linux.
