I went with just text, point-and-click directions initially so people can at least intuit how they’d reverse any changes. I may consider making a scripted solution in the future, but no promises ;)
The majority of things can be done via the Settings app. Some are Local Group Policy settings. There’s a few PowerShell commands to remove pre-installed packages. There’s only 2 or 3 registry tweaks.
If there’s any bugbears, create an issue. I’ll be responding to them every few weeks.
