Windows 2.0 is a 16-bit Microsoft Windows graphical user interface-based operating environment that was released in November 1987 and superseded Windows 1.0. With Windows 2.1x in 1988, Windows 2.0 was supplemented by Windows/286 and Windows/386. Windows 2.0, Windows/286 and Windows/386 were superseded by Windows 3.0 in May 1990, but supported by Microsoft for fourteen years, until 31 December 2001.

Application support

The first Windows versions of Microsoft Word and Microsoft Excel ran on Windows 2.0. Third-party developer support for Windows increased substantially with this version (some shipped the Windows Runtime software with their applications, for customers who had not purchased the full version of Windows). However, most developers still maintained DOS versions of their applications, as Windows users were still a distinct minority of their market.
Applications shipping with Windows 2.0:

1. CALC.EXE
2. CALENDAR.EXE
3. CARDFILE.EXE
4. CLIPBRD.EXE
5. CLOCK.EXE
6. CONTROL.EXE
7. CVTPAINT.EXE
8. MSDOS.EXE
9. MSDOSD.EXE
10. NOTEPAD.EXE
11. PAINT.EXE
12. REVERSI.EXE
13. TERMINAL.EXE
14. WRITE.EXE

Windows NT logo

Windows NT is a family of operating systems produced by Microsoft, the first version of which was released in July 1993. It was originally designed to be a powerful high-level-language-based, processor-independent, multiprocessing, multiuser operating system with features comparable to Unix. It was intended to complement consumer versions of Windows that were based on MS-DOS. NT was the first fully 32-bit version of Windows, whereas its consumer-oriented counterparts, Windows 3.1x and Windows 9x, were 16-bit/32-bit hybrids. Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Home Server, Windows Server 2008 and Windows 7 are based on Windows NT, although they are not branded as Windows NT.
Although various Microsoft publications, including a 1998 question-and-answer session with Bill Gates, reveal that the letters 'NT' were expanded to 'New Technology for marketing purposes, they originally stood for "N-Ten," the codename of the Intel i860 XR processor for which NT was initially developed. However, they no longer carry any specific meaning.

Windows NT 3.1 is the first release of Microsoft's Windows NT line of server and business desktop operating systems, and was released to manufacturing on 27 July 1993. The version number was chosen to match the one of Windows 3.1, the then-latest operating environment from Microsoft, on account of the similar visual appearance of the user interface. Two editions of NT 3.1 were made available, Windows NT 3.1 and Windows NT Advanced Server. It was succeeded by Windows NT 3.5 in September 1994.
It could run on Intel x86, DEC Alpha, and MIPS R4000 CPUs.

Windows 95 is a consumer-oriented graphical user interface-based operating system. It was released on August 24, 1995 by Microsoft[2], and was a significant progression from the company's previous Windows products. During development it was referred to as Windows 4.0 or by the internal codename Chicago.
Windows 95 was intended to integrate Microsoft's formerly separate MS-DOS and Windows products, however it is still considered an operating environment that sits over the DOS operating system. It features significant improvements over its predecessor, Windows 3.1, most notably in the graphical user interface (GUI) and in its simplified "plug-n-play" features. There were also major changes made at lower levels of the operating system, such as moving from a 16-bit subsystem to a 32-bit subsystem.
In the marketplace, Windows 95 was a major success, and within a year or two of its release had become the most successful operating system ever produced. It also had the effect of driving other major players in the DOS-compatible operating system market out of business, something which would later be used in court against Microsoft. Some three years after introduction, Windows 95 was succeeded by Windows 98.
