There are two ways of doing this:
Windows is better for desktop computers. Linux is better for servers.
There are actually 5 major computer families. These include Windows XP, Windows Vista, Mac OS X, Windows 2000, as well as Linux.

A desktop uses the same OS as any other computer, Windows, Mac OS, or Linux. Also, I'd recommend Mac OS X if you're getting a new computer. Here's the scoop: if the computer has an  on it, it runs Mac OS. If not, it runs Windows or Linux.
Any of the operating systems such as macOSX, Linux, and Windows will run on a desktop or notebook computer. The types of operating systems that work on a mobile computing device depend on its type.
Different operating systems have differing features, though they all have the primary function of controlling the software and programs running on a computer or other device. Popular features include: A start menu or application menu (Windows, Linux) Multiple desktop workspaces (Linux, Mac OS X) Taskbar (Windows, Linux) or dock (Mac OS X, also Linux) to track favorite program shortcuts and active applications A desktop environment. Linux has GNOME or KDE (and a few others), Mac has Aqua, and Windows Vista has Aero. Desktop acceleration (Mac OS X, Linux using Compiz or similar, and Windows Vista Premium, Business, or Ultimate)
A quick and relatively easy method of getting Ubuntu Linux - if you already have a Windows system and you want to run Ubuntu Linux on it - is to download Ubuntu and install it by using the Wubi (the Windows-based Ubuntu Installer) from this Ubuntu web site: http://wubi-installer.org You can use the Wubi (Windows-based Ubuntu Installer) to download and install Ubuntu Linux in Windows and this is very similar to installing any software program in Windows. One of the great benefits of using the "Wubi Installer" is that you can also uninstall Ubuntu Linux from Windows if you need to (in the same way as you uninstall any Windows program). When you use the "Wubi Installer", you DON'T have to do the following steps (that you would "typically" need to do) to install the Desktop version of Ubuntu Linux on an existing Windows system: download a Linux ISO file burn the Linux ISO file to a Linux CD set up your computer to boot from CD boot with the Linux CD to run Linux "Live" and get to the GNOME desktop double-click on the "Install" icon to start the installation routine run the Ubuntu Linux installation routine Ubuntu Linux Training Tips: The Wubi Installer is only used to install the Desktop (not Server) Edition of Ubuntu Linux on an existing Windows system - and not on a new or used computer system that doesn't have Windows already installed on it. All of the "download, burn, setup, and so on" steps listed above will be described shortly in upcoming sections. The Ubuntu Linux installation steps described above are required to install the Desktop and Server Editions (versions) of Ubuntu Linux - either on a computer system that has Windows (to create a Dual-Boot Windows / Linux system) or one that doesn't have Windows Ubuntu Linux Training Tips: Keep in mind that prior to installing Ubuntu Linux (or any Linux distro) on an existing Windows system, you need to do a complete backup of your Windows system - twice! Also make sure that you can use the backups that you have created to restore your Windows system from backup.

Windows and Linux use device letters to identify each storage device on a computer.
desktop
Mac, Windows, and Linux.
yes
instead of windows you can have linux or mac. they are different, but you will know whats best for you when you try them, linux is free to download.but you need an operating system (windows, mac, linux or any other OS) for the computer to work
