Log On, User Switching, Locking, and Log Off in Windows Vista

You can use Windows Vista in workgroup configurations and domain configurations. Workgroups are loose associations of computers in which each computer is managed separately. Domains are collections of computers that you can manage collectively by means of domain controllers, which are servers running Windows that manage access to the network, to the directory database, and to shared resources. Typically, home users will use Windows Vista in workgroup configurations and businesses will use Windows Vista in domain configurations. Although all versions can be used in workgroup configurations, you cannot use the home versions in domain configurations.

In a workgroup configuration, Windows Vista displays the Log On screen at startup. All standard user and administrator accounts that you’ve created on the computer are listed on the Log On screen.

To log on, click the account name. If the account is password protected, you must click the account name, type the account password, and then click the arrow button.

In a domain configuration, Windows Vista displays a blank startup screen after initializing the operating system. You must press Ctrl+Alt+Del to display the Log On screen. By default, the last account to log on to the computer is listed in computer\username or domain\username format. To log on to this account, you type the account password and then click the arrow button. To log on to a different account, click the Switch User button, and then click Log On As Another User. Type the user name and password, and then click the arrow button.

Keep the following in mind:

• If the account is in the default domain, you don’t have to specify the domain name.
• If the account is in another domain, you can specify the domain and the account name using the format domain\username, such as cpandl\williams.
• If you want to log on to the local machine, type .\ username where username is the name of the local account, such as .\williams.

Both the workgroup and the domain configurations of Windows Vista allow fast user switching. You can easily change passwords, lock a computer, and log off as well.

Switching Users

To switch users: clicking Start, clicking the Options button to the right of the Power and Lock buttons, and then clicking Switch User.

Or You can switch users by following these steps:

• In a domain configuration, a screen appears with the message “Press Ctrl+Alt+Del To Log On”. To display the Log On screen, you must press Ctrl+Alt+Del again.
• Once the Log On screen appears, you can log on to another account using a technique similar to logging on at startup.

Changing Passwords

You can change passwords by following these steps:

1. Press Ctrl+Alt+Del, and then click the Change Password option.

   The account name for the current user is listed on the change password screen. In a domain configuration, the user account name is listed in domain\username format. In a workgroup configuration, the local user account name is listed.
   

   Tip: By clicking in the User Name text box, you can change the account name. Specify the domain and the account name using the format domain\username, such as cpandl\williams. Type .\ username where username is the name of the local account, such as .\williams.

2. Type the current password for the account in the Old Password text box.

Note:

• If you cancel the logoff, you can resolve the issue with the problem program—for example, by saving your work and exiting the program.
• If you continue logging off by clicking Log Off Now, Windows Vista will force the program causing problems to close, and you might lose work as a result.
