PoL User Backups

I wanted to post this in support but like.. it's not windower or site related. So I guess it goes in general for now. Admins can move it if they want.

I was tinkering around with backing up PoL user directory. I found that this does not work with clean installs of windows/PoL. The user will just get gibberish and be forced to wipe the "login_w.bin" in order to fix it.

It'd be really nice to fresh install 11 and not have to be forced to redo the entire user entry list each time windows decides it needs to be reinstalled or say when a new pc comes along.

Is there a way to fix this?
