Answer 1

These are usually described in the Windows Software Logo Program (link broken). The link is to the Windows 7 logo requirements document, but similar documents exists for XP, Windows 2003, Vista and Windows 2008. In the Technical Requirements section you'll find some of the information you're looking for:

All application data that must be shared among users on the computer should be stored within ProgramData

All application data exclusive to a specific user and not to be shared with other users of the computer must be stored in Users\\AppData

In “per-machine” installations, user data must be written at first run and not during the installation. This is because there is no correct user location to store data at time of installation.

EDIT:

Windows 10 users, look for the Certification requirements for Windows Desktop Apps (Section 10)
