What are we supposed to do with it?
Fix the registry of your friends and family of course!
Also, probably for wine/proton/umu since they use registry files as well.
I’ve used a registry editor on Linux before to pull the Bluetooth pairing keys off my Windows partition so I could add them to my Linux Bluetooth config so the Bluetooth device would work on both systems.
Could you please explain a bit, do you mean that otherwise your bluetooth device would not auto-connect to both devices?
I mean, you probably can’t use them simultaneously anyway?
I think they meant that they copied the keys from Windows to Linux so that they can easily pair their Bluetooth device without having to repair when booting into the other OS.

So without doing it, I think you have to forget and repair every time you want to connect your Bluetooth device if it was paired with the other OS. If keys are copied, you can just connect it without hassle. I did it so that I can pair my controller by just pressing its Power button, and it does not worry about whether my computer is running Linux or Windows.
I guess for WINE and Proton maybe.
Proton’s registry files are text, this tool isn’t needed for that.
