What is an application?
A program that runs “on top” of the operating
system (OS), that helps a user perform a task like
playing media, web browsing, or creating a
document.
Common examples:
 Google Chrome
 Microsoft Office
 Windows Media Player (Native App)

Native Applications
An application that has been developed for use on a
particular platform or device.
Microsoft Windows has several:
 Internet Explorer
 Snipping Tool
 Windows Media Player

Internet Explorer
Web browser application
Newest version claims to:
 Be faster and less cluttered
 Include more privacy settings
 Have better usability features

Snipping Tool
An application that allows you to take screen shots,
annotate them, and save them.
A capture can be:
 A screen
 A window
 A rectangular portion of the screen
 A free-form image.

Media Player v. 12
An application that allows you to play back music,
video files and view photos.
Streaming digital media files—audio, video, or
photos—for playback or viewing from another
computer or a server that hosts Windows media files
is possible.

Media Center
A multi-faceted application that provides a complete
entertainment system for your computer.
Similar to Windows Media Player, but in addition you
can watch, pause, and record HDTV, watch live TV
and online programming, and listen to radio stations.

Local vs. Network Applications
Local installation:
 Simple, all files on local machine.
 For applications that must be able to run with or
without network/internet access.
Network installation:
 Requires more configuration, files on a server.
 Network applications usually need network
access to install, launch, and run.
 Offers administrators greater control over the
app’s access rights.

Local Installation Process
Find and run Setup.exe or a Microsoft installer
(*.msi).
Follow the prompts until finished.
Common installation prompts:
 License agreement
 File location
 Product key

Network Installation Process
Goes beyond the scope of this course due to server
configuration, but we will provide a basic overview of
how it’s done.
1. Set up a domain with Active Directory Domain
Services (AD DS).
2. Create a Group Policy (GP) telling the server how to
install the new application.
3. Create a Group Policy object (GPO) to link the new
GP with a specific group of users or computers.

12
What is AD DS?
A role that can be assigned to Windows servers.
It requires the server to be in a Domain.
 A network in which all users, computers,
printers, and security are registered with a
central database (active directory) that is located
on one or a cluster of central computers known
as domain controllers.
Then, provides network with an Active Directory.
 Storage space on a Windows server for objects
and information that the server needs to
perform its role.

13
What are GPOs-Group Policy Objects?
An object that links a Group Policy to the computers
and users within its control.
 For example a GPO takes a collection of settings,
a GP, and applies them to a specific set of users
or a specific set of computers.
Group Policy - A collection of settings (policies)
stored in an Active Directory.
 For example, settings of what users are and are
not allowed to do like access certain folders.

Network Installation Using Group Policy
A GPO (arrow) is the link that applies the GP to the
Organizational Unit (OU). In this case it limits sales people from
changing Admin files.

Network Installation Summary
If all that was a bit much to absorb, don’t worry…
What you need to know for the MTA:
 With Microsoft Windows and Windows Server,
GPOs can be used to install applications through
the network.
We will now look at the two ways network
installation can be carried out.

16
Assign an App
Using Group Policy, administrators can “assign” or
“publish” applications.
Assignment can be done by computer, computer
group, user, or user group.
 If a new app is assigned to a computer:
• The next time the PC boots up and a user
with correct permissions logs in the app will
install itself.
 If a new app is assigned to a user:
• The next time that a user logs in and selects
the application it will install itself.

17
Publish an App
Publishing makes apps available to users.
Apps do not install unless the user chooses to install
them.
A dialog box will appear at log on asking permission
to install the application.

18
Application Removal
Local removal is done by using the Programs and
Features applet of the Control Panel.
Some applications come with their own
uninstallation software that may be more thorough.

19
Application Removal
Be aware that many uninstallers do not remove the
files created by that application (e.g. documents left
by Office).
Network application removal is handled only by the
administrators, and can be carried out by a Group
Policy as discussed earlier.

What is a Service?
An application that runs in the background on a
Windows machine to help the OS run other
programs and services.
Many services depend on other services in order to
function.
Services Console is the central management point of
services in Windows.

An Example Service
The WLAN AutoConfig service in Windows 7 is what
allows users to easily:
 Discover wifi networks
 Connect to wifi networks
 Configure wifi networks
 Disconnect from wifi networks.
Without this service, users would need to install a
third party software package to access wireless
networks.

Service Accounts
In order for services to operate, they often need
elevated privileges.
Service accounts exist in Windows to permit the
services to function without interruption.
The three default service accounts are:
 Local Service
 Local System
 Network Service.

Service Accounts
Here’s a shot of the Windows Firewall service that uses
the Local Service account to function.

25
Service Dependencies
Recall that without the WLAN AutoConfig service,
wireless access would require more work.
In order for the above service to work it “depends”
on other services, too.
Without the other services listed in a service’s
dependency tab that particular service cannot
function.

Service Dependencies
The dependency tab shows the services required for
WLAN AutoConfig to work.

Managing Services
If services need to be administered, the Services
console is the most effective place to manage them,
but not the only one.
Methods for managing services:
 Services console
 Services tab in MSCONFIG
 Services tab in Task Manager.
© ExplorNet’s Centers for Quality Teaching and Learning
28
Managing Services
The Services console
can be accessed by
typing “services” or
“services.msc” in the
Start menu Search bar.

29
Managing Services
To access services via MSCONFIG, simply type
“msconfig” in the Start menu Search bar and click on
the Services tab.

Managing Services
To access services via
Task Manager click on
the Services tab after
launching Task Manager
window.

Service Startup Options
The most common management done on a service is
altering it’s startup types.
 Automatic (Delayed Start): The service starts
approximately two minutes after the system has
completed starting the operating system.
 Automatic: The service starts as the operating
system starts.
 Manual: The service must be started manually,
by a user, a dependent service, or a program.
 Disabled: The service is disabled and will not
start.

Service Startup Options
Changing the Startup
type is done on the
General tab of a service.
