Computers that aren’t accompanied by a Windows 7 installation disc when they are sold or shipped often come with ‘recovery discs’ or ‘recovery partitions’ that are meant to be used to restore them to the exact way they were when they were taken out of the box.
In such cases, users can end up stumped if they ever need to reinstall Windows 7 on their computers. Many Windows computers that come with Windows 7 out of the box are sold and shipped without Windows 7 installation discs, and many Windows 7 users end up misplacing or losing track of their Windows 7 installation discs.
