==Versions and Backstory==
With the release of Windows 3.0 being the company's major success on computers, Microsoft began to toy around with a project that was codenamed Marus. After some employees showed it to company executives, the project was given the green light for release.
Pre-alpha versions of the system would eventually be available using the Madden Developer Channel from September 1990 to November 1991. In April 1992, the final name was chosen. Alpha variants popped up beginning in August 1992 and finishing in April 1993. 
Beta 0 was released to developers on April 15th, 1993. Beta 1 followed on September 16th, 1994. Beta 2 would soon be released to developers in January 1995, with Beta 3 arriving on February 13th that same year. The final beta release was made available in April 1995.
Release candidates 1 and 2 were eventually released in mid-1995. Windows 4.0 would then be released on the same day as Windows 95, which was soon called Windows 4.0: 9x Edition. Windows 4.0 Plus was released the same month as Windows 4.0: 9x edition. MME 2.0 followed in October.
The Professional and Server editions came out later in November, followed by 4.1, codenamed Armagh, and Workgroups 4.1, codenamed Strasburg. Windows for Workgroups 4.11 was released in December 1995 and was codenamed Seymour.
In January 1996, Windows 4.0 received its first service pack release. Windows 4.2, which was designed for the US and Chinese markets, was later released and codenamed Tennga. Windows 4.3, codenamed Cajon, came out in May 1996 but got recalled in August 1996 due to a critical security flaw. The re-release variant arrived on the market in September 1997. In July, Windows 4.0 got its second service pack, with Windows 4.4, codenamed Cayce, being released in August 1997.
From April to July 1998, the Windows 4.5x line of systems was released. The two versions were 4.5 and 4.51. Windows 4.6, codenamed Quintinshill, in November 1998 followed this series.
In February 1999, Windows 4.7, codenamed Ceres, was released. In September, Windows 4.0 received its third service pack, and in December, Windows 4.8, codenamed Moon Summit, was released.
Windows 4.9, codenamed Weyauwega, was released in August of 2000 and was the last Windows 4 branded system to be based on MS-DOS. From Service Pack 4 onwards, all Windows 4 systems were based on the much more stable Windows NT code.
