I have a couple of questions on Win7:

1) By default, some programs install into the Roaming folder (c:/users/username/AppData/Roaming) while some install into the Program Files folder (c:/Program Files). What is the difference between these two folders? Why can't just one folder i.e. Program Files be the default installation folder as in XP?

2) What is the purpose of the virtual D: drive "Recovery"? Is this really needed and is there an option to remove it?

Thanks
