Only time I reinstalled Windows on a laptop was when I was trying to get an ODB2 over USB connector to work, and the program (FORSCAN) couldn't automatically read the device in Wine. You had to run a series of commands to find the device and then create a symlink in that Wine prefix. I was not going to tinker around like that while sitting in a hot car upon the hope I get it right and don't fuck up the instrument cluster.

But besides those weird edge cases, it's been pretty easy for me too, and I still reinstalled Linux after that little project!

Now that I think about it, I wonder if a Windows VM would have worked...
