Whenever I set up a new computer for older family members, despite it being windows 11, I always install open shell[1] and retro bar[2]. Between the two, I've made the operating system look very close to Windows XP visually, and they always appreciate it.

I'm still on Win10, but I use WindowBlinds to skin it to look like Win2K. Eventually, when I upgrade my CPU, I'm going to need Win11 to get the Intel Thread Director, so I know I'm going to need to either buy a new version of WindowBlinds and Start11. Would be nice to run a FOSS alternative.
