And since I think v1803 or earlier you can basically do an OSX like in place reinstall keeping your files and apps or just files not to mention the actual Reset feature built into recovery that can do this without an install disk/usb. Quick, simple, and works very well unless the OS is shredded by bad GPOs or other changes most users won't be able to do themselves.

I don't think the author was up to speed on caring for their Windows install or simply messed with it enough to break it over time and should have been prepared for the issues that brings. I've stuck to a pretty clean W10 install since mid 2015 so when I reinstall I'm up and running after Ninite and a few other installs I keep on a file share like specific drivers or apps I don't want to download again. W10 is fairly robust unless you do things to break it like click through UAC prompts, edit Windows dir files without backups, or install unvetted software from the internet (spoiler: same wisdom applies to OSX and Linux)
