I have Windows 7 Pro with 8 gigs of ram, and I frequently have more than one user logged on, such as my user logged on in the background downloading torrents while the kids are surfing on line in the foreground. Is it possible to remote into the background user account to be able to say add more torrents, or copy files over the network without kicking the kids off? I have windows XP on an old laptop on the network, and would like to be able to access from work as well running windows 7. I want to do more than just share files, that I know how to do. So question is what software should I use?
