The right operating system (OS) can make the difference between a functional computer and one in need of an upgrade. Software affects all of a device's processes and can improve its functionality. Every user should work with an OS that they are comfortable with and can navigate easily.

Microsoft Windows and its many versions have maintained steady levels of popularity due to their familiar menus, tools and interfaces. For example, the two latest Windows operating systems, 7 and 8, have kept user-favorite features while upgrading other content.

Windows 7 has been a popular Windows OS due to its intuitive design, which is much more user-friendly than that of previous generations. On-screen navigation has been simplified with a larger, customizable taskbar, so popular applications can be opened with only a single click.

While there are many versions of Windows 7, Ultimate offers increased security and data backup. The OS comes with BitLocker, a hard drive encryption program. Windows 7 Professional offers advanced storage, as well, which prevents unsaved documents from being lost during hardware malfunctions.
Windows 8 is the latest version of Microsoft's flagship operating system. The platform features interfaces that have been optimized for mobile and desktop computing, though both menus can be used easily on computers and tablets.

Users don't have to buy new laptops to use Windows 8, because multiple versions of the OS are available. Windows 8 is the basic OS upgrade, providing users with new features such as the tiled start screen and downloadable apps from the Windows Store. Windows 8 Pro includes BitLocker and remote desktop sharing, making it the optimal choice for professionals who need to use their home computer for work.
