Overview

Introduction

The Understanding Executable Files module provides you with the instruction and devices to develop your hands on skills on the defined topics. This module includes the following exercises:

  • Working with .EXE files
  • Working with .MSI files
  • Working with .APP files
  • Working with .BAT files

Exam Objectives

The following exam objectives are covered in this lab:

  • FC0-U51: 1.3 Given a scenario, use software management best practices (Install/uninstall).

Exercise 1 - Working with .EXE files

.exe files are traditionally used to install applications on a computer. .exe files, when executed, call different functions and other support files automatically based on user input. In this exercise, you will install and explore the common features of executable (.exe) files.

Exercise 2 - Working with .MSI files

Microsoft installer or MSI (also known as Windows installer), files are normally used for installing, storing, and uninstalling programs. MSI files contain the installation logic on how to install the application as it contains information about system requirements, features, components and the installation wizard to be used. MSI files are mainly used by software vendors to distribute applications to their customers.

Applications installed using .exe files or .msi files behave similar. However, programs installed using MSI technology are self-repairing and normally do not call for a complete reinstall.

Files with an extension name .msi are used only for initiating a program installation. While files with .exe extension name can either be used for launching a program or start with a program installation. The .msi files are executed by MSIEXEC.EXE also known as Windows Installer service.

In this exercise, you will install and explore MSI files.

Exercise 3 - Working with .APP files

APP (application) files are XML-based executable file supported by Windows 8.x operating system. APP files can install various types of commercial, shareware, or freeware applications on your computer. An app, when installed, creates a tile within the Windows Start screen that you can click to start the application.

In this exercise, you will download and install APP files from the Windows store.

Exercise 4 - Working with .BAT files

Batch files, identified as the .bat files, were used in the early days of disk operating system (DOS) and legacy Windows (Windows 9x) to run programs like anti-virus and other utilities while a user logs on to a computer. These files operate from the command prompt of the computer. Shell scripts are the batch file-counterparts for Unix and Unix-like operating systems, such as Linux.

Newer versions of Windows have replaced batch files with programs such as System Configuration (msconfig.exe) to initialize services or applications upon user logon. In this exercise, you will create a simple batch file to run commands on the command prompt. You will also verify that the batch files can run as command prompt files as well.
