Windows 95
Chicago
Win 95

    (Win95) Microsoft's successor to their
   Windows 3.11 operating system for IBM PCs.  It was known
   as "Chicago" during development.  Its release was originally
   scheduled for late 1994 but eventually happened on 11 Jul
   1995, followed by Service Release 1 on 1995-12-31 and OSR2
   (OEM Service Release 2) on 1996-08-24.

   In contrast to earlier versions, Windows 95 is a complete
   operating system rather than a graphical user interface
   running on top of MS-DOS.

   It provides 32-bit application support, pre-emptive
   multitasking, threading and built-in networking (TCP/IP,
   IPX, SLIP, PPP, and Windows Sockets).  It includes
   MS-DOS 7.0, but takes over completely after booting.  The
   graphical user interface, while similar to previous Windows
   versions, is significantly improved.

   Windows 95 has also been described as "32-bit extensions and a
   graphical shell for a 16-bit patch to an 8-bit operating
   system originally coded for a 4-bit microprocessor, written by
   a 2-bit company that can't stand 1-bit of competition".

   The successor to Windows 95 was Windows 98.
