Recently (last year?) Microsoft enabled publishing MSI/EXE applications to Microsoft Store. My question is, how isolated is the application installed via the store. Appreciate if somebody could point me to a basic article describing the store architecture related to MSI/EXE applications in the Microsoft store.
To be more specific, I am looking for answer to interoperability questions like: can an application installed via Microsoft store access windows registry? If yes, can it change the registry and will these changes be visible to other (installed) applications, (or virtualized?) Will COM/DCOM calls work? Will named pipes work?
To summarize in one question, what level of isolation is built around an MSI/EXE application installed via store, if any?
