I basically never want to use the feature. How to? There's another question here that answers how to disable it in Linux via a command-line option in .bashrc, but I don't think that can be done in Windows?
Edit: Additional information:
I am on Windows 10
No Recovery.xcu anywhere on my C drive.
even if I discard recovery data, then the next time I open the same file there is no recovery prompt. But when I shutdown Windows without shutting down LibreOffice first, then I get the prompt the next time I open the file.
