On the General tab, you may modify the following settings by checking the appropriate box:

A note about disabling user accounts: A common administrative practice is to disable an account rather than delete it when an employee leaves. That way, if another user replaces that staffer, you can simply rename and reenable the account, and the new employee will have all the same settings as the previous one.

The Guest account: Windows 7 includes an account named Guest, which has a bare minimum of permissions and is disabled by default. If you want to use this account, click Local Users and Groups, expand Users, double-click on the Guest account, and clear the Account is disabled check box.

Managing groups: Every Windows account is a member of at least one group. Group membership defines what set of permissions each account has. Most people use the groups built in to Windows (called Account Types when you're in the Create User wizard), but you are free to create and customize your own. Groups exist to make administration of a computer easier by allowing the administrator the flexibility to apply permissions and policies to more than one account simultaneously.

Besides Users (or Standard Users) and Administrators, you'll find a multitude of other groups in Windows 7. Some of these are intended for backward-compatibility, while others are designed for specialized purposes such as allowing access to back up and restore files, to read log files, or to connect through Remote Desktop.
