CompTIA A+ Certification All-in-One Exam Guide

just a single user account. You can make a group called Accounting, for
example, and put all user accounts for the accounting department in that
group. If a person quits, you don’t need to worry about assigning all the
proper access levels when you create a new account for his or her
replacement. After you make an account for the new person, just add her
account to the appropriate access group! Second, Windows provides
numerous built-in groups with various access levels already predetermined.
While all versions and editions of Windows come with many of these
built-in groups, Windows Home editions handle these very differently than
more advanced editions. For starters, make sure you are aware of the
following groups for the exam:
• Administrators Any account that is a member of the Administrators
group has complete administrator privileges. Administrator privileges
grant complete control over a machine. It is common for the primary
user of a Windows system to have her account in the Administrators
group.
When you create the Jane user account, in other words, and make Jane
an administrator, you place the Jane account in the Administrators
group. Because the Administrators group has all power over a system,
Jane has all power over the system.
EXAM TIP Note that the default administrator account is Administrator.
You should use this default only if no other administrators can log on. Best
practice is to make a complex password for Administrator; write it down, and
put it in a safe for emergency use. Change the default admin user
account/password to reflect one or more of the user accounts added to the
Administrators group.
• Power Users Members of the Power Users group are almost as
powerful as members of the Administrators group, but they cannot
install new devices or access other users’ files or folders unless the
files or folders specifically provide them access.
