Just so you don’t make the same face palm inducing mistake I did:
Moving Roon from MacOS to Windows was no problem for me.
But while doing so I realized the USB drive containing my music was formatted for Apple so Windows could read it but not write to it.
I had to buy another drive formatted for windows and transfer my music to it.
Roon recognized the new drive without issue though.
All my Roon edits etc. were preserved.
