Visual J++ (1996) 0 Windows

Visual J++ was Microsoft's proprietary dialect of the Java programming language which ran on Windows under Microsoft's Java virtual machine. It was part of the Microsoft Visual Studio product lineup. It included an Integrated Development Environment and many language extensions, such as the ability to make efficient use of the Win32 APIs. The primary advantage of J++ and Java was the ability to run on a byte-code virtual machine (pioneered by languages like the UCSD P-System ) at a time when Intel was threatening to cut off x86 compatibility in favor of 64-bit instruction sets.

Win32s (1992) 6 Windows

Win32s (Win32 subset) was an API layer for Windows 3.1 and Windows for Workgroups that allowed some Win32 applications that compiled with the subset of Windows NT API functions supported through 32->16 bit thunks. Certain functions such as threading and OpenGL were not supported. As Windows 3.1 was cooperatively multi-tasked, so are Win32s applications on 3.1 and memory space is still shared.

Windows 1.0 was the first release of what eventually made it onto almost every desktop computer in the entire world. Many of you are probably unaware of this release from 1985; conceived from ideas found in the original Lisa/Macintosh and Xerox Star system, Windows 1.0 was Microsoft's attempt at a graphical multitasking operating environment for the IBM PC. | 1.0 | 2.x | 3.x | NT 3.x | 95 | NT 4.0 | 98 | 2000 | ME | All |

Windows 2000 (1999) 710 Windows

Windows 2000 was a modernization of Windows NT 4.0 which brought many of the desktop changes, including Active Desktop, to Microsoft's Windows NT line. Four editions of Windows 2000 were released, Professional, Server, Advanced Server, Datacenter Server. Improvements over NT 4.0 include new Accessibility Options, increased language and locale support, NTFS 3.0, the Encrypting File System and Active Directory. Windows 2000 was first planned to replace both Windows 98 and Windows NT 4.0 although using the NT kernel for consumer and professional editions would not happen until Windows 2000's successor, Windows XP. | 1.0 | 2.x | 3.x | NT 3.x | 95 | NT 4.0 | 98 | 2000 | ME | All |

Windows 3.0 / 3.1 (1990) 660 Windows

Windows 3.x was the first to gain significant development and commercial traction. It combined the 8086, 286, and 386 modes of Windows 2 in to one package. It replaced the MSDOS Executive with a Program Manager and File Manager similar to those in OS/2 1.x. Much of its success was spurred by the availability and success of Microsoft Office. Although Microsoft would have had you believe otherwise, Windows 3.x was the direct foundation for Chicago/Windows 95. | 1.0 | 2.x | 3.x | NT 3.x | 95 | NT 4.0 | 98 | 2000 | ME | All |

Windows 95 offered, at long last, a well designed document-oriented desktop shell that worked much like the 1984 Macintosh Finder.

Windows 98 is a continuation of the Windows 95 product. The major change is an insanely heavy focus on web integration. The help system, many applications, and even the desktop are redesigned to make use of Internet Explorer. Windows 98 runs on top of the same "MS-DOS 7.1" with FAT32 support as Windows 95 OSR2, and it includes support for USB. Windows 98 had two major releases - a First Edition and a Second Edition. It was followed up by Windows ME. | 1.0 | 2.x | 3.x | NT 3.x | 95 | NT 4.0 | 98 | 2000 | ME | All |

Windows Longhorn (2001) 376 Windows

Windows Longhorn was the pre-release codename for Windows Vista and was the successor to Windows XP and Windows Server 2003 (built from NT 5.2 codebase). Development on the OS started in May 2001 and went through two unique development cycles separated by a development reset in 2004. The reset occurred as Microsoft's development staff had lost focus on the project as a whole and what was required to be done in order to bring it to market. Features were being written into the OS at an alarming rate with a significant lack of QA or vision of true requirement. This combined with Microsoft's trustworthy computing initiatives caused the reset.

Windows Millennium Edition (internally Windows 4.90) was the last in the line of DOS-based Windows products.

Windows NT 3.x (1991) 276 Windows

Windows NT 3.1 was the first of the Windows NT series. Sporting the same face as its consumer counterpart Windows 3.1, it was completely different under the hood. A true 32-bit native operating system, Windows NT descended from the work Microsoft did while collaborating with IBM on OS/2 after the great split, and bringing in former DEC employees like Dave Cutler, bringing a VMS influence into the system. It was followed up by Windows NT 4.0. | 1.0 | 2.x | 3.x | NT 3.x | 95 | NT 4.0 | 98 | 2000 | ME | All |
