Computer windows installation


COMPUTER WINDOWS INSTALLATION:Installation is the process of making hardware and/or software ready for use. Obviously, different systems require different types of installations. While certain installations are simple and straightforward and can be performed by non-professionals, others are more complex and time-consuming and may require the involvement of specialists.

Windows Installer is a utility application in the Windows operating systems that is used for installing software/applications. It provides a means to install software on a computer that complies with the architectural framework of Windows. Windows Installer was previously known as Microsoft Installer.

An installation program or installer is a computer program that installs files, such as applications, drivers, or other software, onto a computer.

Windows Installer is primarily designed for software publishers that design and develop software/applications for Windows. Typically, each third-party software is bundled with the Windows Installer. This binding allows the correct installation and configuration of a third-party application on a Windows framework. Windows Installer has been released in different packages that generally include the following:

  • Database and guidelines for developing an installer for applications and services
  • Transformations, modifications and version control
  • API for remotely accessing installed applications/software

Windows Installer has an “.msi” extension and usually includes an application for uninstalling the program/software. The uninstaller is usually invoked from the Control Panel.

What are the two types of Computer windows installation?

Installation can be categorized into two broad categories:

  1. Physical computer windows Installation.

Physical installation pertains to installing physical equipment such as computer hard drives, cables, modems and so on.

  1. Virtual computer windows Installation

virtual installation refers to installation of software.

Much physical machine installation requires specific expertise. Similarly, there are software installations that can be done only by experts, whereas other installations are as simple and straightforward as the wizard-based installations commonly found with consumer software and frequently available on websites to be downloaded.

Different types of software installations include Windows Installer installation, web-based software installation and single exe software installation.

How to install Microsoft windows operating system

Each version of Microsoft Windows is installed on a computer using similar steps. While there are steps in the installation process that differ between versions of Windows, the following general steps and guidelines help you install Windows on your computer.

Installing Windows might sound like a daunting task, but it’s really quite easy, especially if you’re installing a more recent operating system like Windows 11, Windows 10, or Windows 8. But no need to take your computer into the local experts for a simple reinstall—you can install Windows all by yourself!

The steps below are for all recent versions of Windows, including Windows 98Windows MEWindows 2000Windows XPWindows VistaWindows 7Windows 8Windows 10, and Windows 11.

These steps even work for earlier versions (e.g., Windows 95) as long as you use the disc version. The floppy diskette version is similar, but it requires additional steps.

Check hardware compatibility

Before installing or upgrading Windows on your computer, check the hardware in the computer to make sure it’s compatible with that version of Windows. Microsoft provides a Windows Compatible Products List for checking if the hardware in your computer is compatible with the chosen version of Windows.

If one or more pieces of hardware is not compatible with the chosen Windows version, we recommend replacing that hardware with compatible hardware or purchasing a new computer. Having compatible hardware in your computer helps ensure the Windows install or upgrade process is successful.

Genuine Windows CD, DVD, or USB thumb drive

First, you need a genuine copy of the Microsoft Windows operating system installation CDDVD, or USB thumb drive. A genuine Windows product key is included with the installation disc, which is required to activate Windows after installation. If you have an OEM (original equipment manufacturer) computer, the Windows product key is often on the back or side of the computer.

If you have an OEM computer (e.g., AcerDellHP, etc.), the computer will not have a genuine Windows CD, DVD, or USB thumb drive. Instead, you would reinstall Windows and the software using a hidden partition or a set of restore discs. The steps mentioned on this page would still work, but you’d need a copy of Windows. You can borrow a friend’s Windows disc, as long as it’s the same version of Windows that came with the computer and have a product key.

To start the Windows install or upgrade process, you need to configure your computer to boot from a CD or DVD before booting to the hard drive. Changing the boot process forces the computer to look for the Windows installation disc before booting from the hard drive.

  1. Open the CMOS setup.

How to enter the BIOS or CMOS setup.

  1. Change the computer’s boot order. Set the CD, DVD, or disc drive as the first boot device if you are trying to boot from a disc. Or, set the first boot device to your USB drive if you’re trying to boot from a USB thumb drive. If the drive is not shown, keep the disc is inserted and reboot the computer. With the disc in the drive, BIOS should recognize and include it in the list.
  2. Save the settings change and exit BIOS.

Once you have updated the boot order, you can begin the Windows installation process.

  1. Place the Windows disc in the CD/DVD drive or USB thumb drive into the back of the computer.
  2. Turn on or restart the computer. As the computer starts up, it should detect the installation disc or drive and show a message similar to Press any key to boot from CD. Press any key on the keyboard to have the computer boot from the Windows disc or drive.
  3. After the Windows install begins, there are several prompts that you need to answer. Select either yesor the appropriate option to install Windows.
  4. When asked which partitionto install Windows onto, select the main partition, usually the C: drive or one labeled “Unallocated partition”. If upgrading Windows, select the existing installation of Windows on the hard drive.
  5. You may be asked if you want to erase all contents on the hard drive, then install Windows. We recommend you choose this option, as it also formats the hard drive to allow the Windows operating system to be installed.
  6. The computer may need to restart several times during the Windows install process. The restarts are normal and if prompted to restart, select the Yes
  7. When the install process is nearly complete, the Windows configuration option screens are shown. On these screens, you may be asked to select the time zone you live in, your preferred language, and the account’s name you use to access Windows. Select the appropriate options and enter the appropriate information on each configuration screen.

The Windows install process is completed when the computer prompts you to log in or when it loads into Windows.

After Windows is installed on the computer, you need to install the drivers and related software for the hardware in the computer. You can use the installation discs that came with the hardware or download the drivers from the hardware manufacturer’s website.
