>Remember how much ridiculousness was in XP? All those colours you could change to make it unusable - why?
Out-of-the-box XP gave users the choice of themes, just select the one you like and XP does the rest, or you could play with colours, this enabled others (ie. intelligent and aware users) to develop other themes, like those that are really useful to those with dyslexia - where one-size-fits-all doesn't apply.
I personally didn't like 95 and later because they took away the option to replace and move around the window furniture; my WfWg desktop used SunView graphics with the window furniture arranged to make things easier for left-handed use. In all versions of Windows since 95, the only concession to left-handed people has been the ability to swap the mouse buttons...
Yes, you could install TweakXP and get easy access to even more settings MS chose to bury in the registery; it seems about the only way to make Windows 11 into something usable is to install Rectify11.
I assume you also dislike all the options GPO gives for playing around with Windows and making it unusable.
