Microsoft has released its latest rendition of the Windows operating system, Windows 7. Windows 7 succeeds Windows Vista and comes with many improvements and useful updates. To install the update one a personal computer running Windows, a backup of the user's personal files and data onto a detachable hard drive is recommended to prevent data loss during the update process. The ISO image of the Windows 7 OS is burned onto a DVD. A partition is optionally created on the user's computer to allow multiple operating systems to be installed. The Windows 7 DVD is then inserted, which installs the OS. Files and applications are reinstalled and additional updates downloaded from Microsoft.
