You can easily set or unset a password so the user has to type a password when they enter Vista, but you may find that anyone running on a network has to (no matter what) type in a password to enter.

There is a quick tweak you can perform that you will let anyone on a network enter Vista without a password, just follow these steps;

  • Open run (start - run)
  • Type in gpedit.msc
  • You need to navigate to this location
    • Computer Configuration
    • Windows Settings
    • Security Settings
    • Local Policies
    • Security Options
  • Double click on this policy;
    • Accounts: Limit local account use of blank passwords to console login only
  • Select disable
  • Click apply and OK
  • Done
Network access with no password
