Earlier quoted context omitted.
I use Win10 at work and the Calc app lags for like 10s when opening before I can type in it. I firmly remember it started to do that after some reboot update ...
I hate the slow right click menu too, why is there a forced delay? I think visual design peaked a few years ago and now we are deliberately overcomplicating every piece of UI for no apparent reason.
It takes away freedom and agency for devs which makes small things also suck where mainly complex things needing multiple programmers did without agile.
Since agile is so process heavy.
I imagine there are no dev owner of calc.exe anymore at MS.
They ruined paint.exe too btw.
