I was playing around with icon sets a while ago, and applied a pack from dA (I think it was this one) using IconPackager. I didn't really like the program's capabilities, it was too spotty, so when the trial ran out I tried to revert things. Some of it wouldn't revert though, so I've got several more modern icons on things.

change background to any kind of gray
turn on "automatically hide the taskbar in desktop mode"
install win10widgetes
install chocolatey package manager
install "winfetch" by typing this into an admin powershell: "choco install winfetch"
and thats it
The window manager is I think a Blackbox variation.
The terminal is Windows Terminal.
