Windows 7: Is it a bad idea to Share the entire 'Users' directory with Everyone?
Solution 1:
If its still asking for your password, its not a huge security risk. (unless your password is blank or really bad).
As long as you have the network at home identified as your "home network" and when you are traveling with your windows 7 computer, you make sure to choose "public network" when you connect to other networks. choosing public networks makes it automatically block the file sharing and a few other things to protect you.
