If you have to use Windows, there are two mandatory apps with which you can turn Windows in an fast, private and submissive OS without nags and trackings, Hellzerg Optimizer and Portmaster. My tweked W11 use less than 1 GB in RAM and the GUI has nothing to do with the (horrible) original one.

















There are two Windows services which are big Data hogs, slowing down the system and which you can desactivate, the hibernation service, which create temporary duplicates of every open app in a temporary file, so it open this apps after Reboot, it’s not really needed, you can put apps you use regulary simply in the Start avoiding to fill your PC with tons of temp files. Apart the Index service, which stored any change in the file system, to accelerate the search, but this in a modern PC, more if you use an SSD, don’t make much diifference, but save a lot of RAM and CPU.
For customize the UI and the Start menu, which in Win 11 is by default an absolute crap with an chunky Fisher Price design, where you can’t customize not even the Task Bar, you can use WindHawk (FOSS), it’s something like an userscript manager, which permits to change any aspect of the GUI with an click.
