Many applications keep settings or configurations in files that later get stored in per-user based locations, such as %appdata% or %localappdata% folders.

With App-V packages closing to end-of-life (2026), the reality of a transition to MSIX is much closer and many are starting to research the ins and outs of what it entails.
