Managing Your User Account
|
631
LocalService
A system account for running services with fewer privileges and logon rights
than the LocalSystem account. The operating system manages this account.
NetworkService
A system account for running services that need network access privileges. The
operating system manages this account.
In most cases, you don’t need to modify these or other default accounts. While you
can configure Administrator and Guest so that you can use them for logon, in most
cases you should use a user account with administrator privileges instead. An admin-
istrator user account is one of two types of user accounts you can create. You can
also create standard user accounts. When a user needs the highest level of permis-
sions possible, create his account as an administrator user account. Otherwise, cre-
ate his account as a standard user account.
Managing Your User Account
Your user account has many properties associated with it. These properties include a
password, picture, account name, and account type designation. At home, you can
manage the properties associated with your user account by following the tech-
niques discussed in this section. Most account management tasks require you to
have an Administrator account or the username and password of an Administrator
account.
At the office, you won’t be able to use these techniques to manage
your account, even if you log on to your computer using a local
account. As discussed previously, when your computer is a member of
a domain, different security components and features are in effect.
Changing Your Account Name
Because your computer tracks your account with an SID, you can safely change your
account name at any time without worrying that this will cause problems with your
access permissions or privileges. If you want to change your account name, follow
these steps:
1. Click Start and then click Control Panel.
2. In the Control Panel, click the User Accounts and Family Safety heading and
then click User Accounts.
3. On the User Accounts page, click “Change your account name.”
4. On the Change Your Name page, shown in Figure 18-1, type the new name for
your account and then click Change Name.
