Disabling Unneeded Services
Disabling Unneeded Services
A service is a software application that runs continuously in the background
while your computer is on. The Windows operating system has numerous
services that run in the background that provide basic functions to the system.
Network connectivity, visual support, and external device connectivity such as
printer services are all examples of the types of services that the Windows ser-
vices provide. Each service that is running in the background takes up system
resources, such as memory and CPU time. Also, during the booting of the
operating system, the service has to be loaded. On most computers, nearly 20
services are loaded upon startup. Of these 20 services, only a handful are system
critical services; all the others can be disabled.
Disabling a service can disable a feature that you or applications installed on
your PC depend on so it is important to know what the services in Windows 8
do. Table 13-2 will help you understand what the most common services are,
what they do, and whether they can be disabled.
Table 13-2: Common Windows Services in Use
ActiveX Installer
Provides UAC validations for Internet-based
ActiveX installs. This only runs when needed.
Application Experience
Provides a compatibility cache for older
applications that caches requests when they are run.
This service can be disabled, but I recommend
leaving it started for application compatibility with
the new architecture of Windows 8.
Application Identity
Verifies the identity of an application. Used by
AppLocker. Does not run unless AppLocker is
in use.
Application Information
Allows you to run applications with all
administrative rights. Keep this service running.
Application Layer Gateway
Provides support for additional protocols for the
Internet Connection Sharing service. You can
safely disable this service.
Application Management
Used for software deployment and management
through Group Policy. If you do not use Group
Policy for software, you can safely disable this
Background Intelligent
Transfers data in the background when the
connection is not in use. One use of this service is to
download updates automatically in the background.
This service is not system critical, but disabling it
can impair other services such as Windows Update.
I would keep this service enabled.
