runas cmd makes your life easier
This week I had to temporaly use a different user on my machine. So at first I thought I had to move all my settings (outlook profile, firefox bookmarks, vms, etc) from my primary user to this new one. This is not a nice task. Hopefully I remembered the runas command which allowed me to run the above programs (indeed I'm currently creating this post running WLW using runas) as my primary user from the new user session. IMO this is definitily a very good tip if you have the same scenario in the feature.
