I let Discover handle updating to Fedora 42 and got a kernel panic error, so I backed up /home/ and did a fresh install of Fedora 42.
I started my restoration by nuking /home/ with sudo rm -R /home/ and then copied everything over via Dolphin as stuff was slowly torn asunder as parts unloaded from RAM. Everything seems intact so far…
Windows uses the system registry to control other aspects of interaction with runtimes and linked libraries, so it can be confusing to people newer to Linux to just realize that flat files don’t have some hidden interaction elsewhere in the system (usually).
