© ExplorNet’s Centers for Quality Teaching and Learning 2 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)
3
© ExplorNet’s Centers for Quality Teaching and Learning 3 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
4
© ExplorNet’s Centers for Quality Teaching and Learning 4 Internet Explorer Web browser application Newest version claims to: Be faster and less cluttered Include more privacy settings Have better usability features
5
© ExplorNet’s Centers for Quality Teaching and Learning 5 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.
6
© ExplorNet’s Centers for Quality Teaching and Learning 6 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.
7
© ExplorNet’s Centers for Quality Teaching and Learning 7 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.

10
© ExplorNet’s Centers for Quality Teaching and Learning 10 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.
11
© ExplorNet’s Centers for Quality Teaching and Learning 11 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
12
© ExplorNet’s Centers for Quality Teaching and Learning 12 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.
13
© ExplorNet’s Centers for Quality Teaching and Learning 13 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.
14
© ExplorNet’s Centers for Quality Teaching and Learning 14 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.
15
© ExplorNet’s Centers for Quality Teaching and Learning 15 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.
16
© ExplorNet’s Centers for Quality Teaching and Learning 16 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.
17
© ExplorNet’s Centers for Quality Teaching and Learning 17 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.
18
© ExplorNet’s Centers for Quality Teaching and Learning 18 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.
19
© ExplorNet’s Centers for Quality Teaching and Learning 19 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.
20
© ExplorNet’s Centers for Quality Teaching and Learning 20 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.
21
© ExplorNet’s Centers for Quality Teaching and Learning 21 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.
22
© ExplorNet’s Centers for Quality Teaching and Learning 22 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.
23

24
© ExplorNet’s Centers for Quality Teaching and Learning 24 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.
25
© ExplorNet’s Centers for Quality Teaching and Learning 25 Service Accounts Here’s a shot of the Windows Firewall service that uses the Local Service account to function.
26
© ExplorNet’s Centers for Quality Teaching and Learning 26 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.
27
© ExplorNet’s Centers for Quality Teaching and Learning 27 Service Dependencies The dependency tab shows the services required for WLAN AutoConfig to work.
28
© ExplorNet’s Centers for Quality Teaching and Learning 28 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.
29
© ExplorNet’s Centers for Quality Teaching and Learning 29 Managing Services The Services console can be accessed by typing “services” or “services.msc” in the Start menu Search bar.
30
© ExplorNet’s Centers for Quality Teaching and Learning 30 Managing Services To access services via MSCONFIG, simply type “msconfig” in the Start menu Search bar and click on the Services tab.
31
© ExplorNet’s Centers for Quality Teaching and Learning 31 Managing Services To access services via Task Manager click on the Services tab after launching Task Manager window.
32
© ExplorNet’s Centers for Quality Teaching and Learning 32 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.
33
© ExplorNet’s Centers for Quality Teaching and Learning 33 Service Startup Options Changing the Startup type is done on the General tab of a service.
