Understanding Windows Vista Personalization

While these features have a far-reaching impact on the way you use Windows Vista,
they enhance security and provide your computer with better protection from mali-
cious programs. If you use these features as they are intended to be used, your com-
puter will be protected from many types of malicious programs.
Turning UAC On and Off
To your own detriment, and I mean that quite literally, you can disable UAC and all
its related features on a per-account basis. Rather than completely disabling UAC,
you can enable and disable individual features through policy settings. As we’ll dis-
cuss in Chapter 18, you can find these policy settings under Security Settings\Local
Policies\Security Options.
At home, you can turn UAC on and off for your account by following these steps:
1. Click Start and then click Control Panel.
2. In the Control Panel, click the User Accounts heading and then click User
Accounts again.
3. On the User Accounts page, click “Turn User Account Control on or off.”
When you click “Turn User Account Control on or off,” you are
prompted for permissions or consent, as discussed previously. Because
this is an inherent part of the user interface and a feature that you can
enable or disable, I will not mention each time the prompt is dis-
played. Rather, I will assume that you provide the permissions or con-
sent as required.
4. To disable UAC, clear the “Use User Account Control” checkbox. To enable
UAC, select the “Use User Account Control” checkbox. Click OK.
5. When prompted, click “Restart now” or “Restart later” as appropriate. You will
need to restart your computer for this change to take effect.
At the office, you cannot turn UAC on and off using this technique. While you may
be able to configure individual UAC features through policy settings, these features
will more than likely be set so that you cannot configure them.
Understanding Windows Vista Personalization
As you’ve seen, many factors can affect your computer’s appearance and perfor-
mance, including your hardware components and account controls. The way you
achieve a balance between appearance and performance, however, is largely through
the trade-offs you make when applying personalization settings, and it is personaliza-
tion settings that largely determine your experience.
