Windows is a series of operating systems produced and maintained by the Microsoft Corporation. It was estimated that as of December 2007[1] Microsoft Windows accounted for nearly 90% of operating system usage, with 3 out of 4 being Windows XP. Windows is used for desktop, and server computers,[2] and more recently also for cellular phones and tablet computers. It is intended for use with the Intel x86-64 family of processors.
Early versions of Windows (98 and earlier) were notoriously unreliable, despite (or maybe because of?) Microsoft's near-monopoly share of the desktop operating system market. They crashed so often that the term "blue screen of death" entered the vocabulary.
Initially Windows was a text-based system (MS-DOS). Then a Graphical User Interface extension was added onto this MS-DOS core[3] It became a full GUI operating system free of the MS-DOS core beginning with the release of Windows NT.
