Windows OMV

Windows Codename Delta is codename of Windows OMV. It is also known as Windows OMV, due to it's name. It is a successor of Windows 2000 Datacenter Server. As for OMV it is named after Austrian petrol station as for Delta it is named after fourth letter of Greek alphabet and seventh letter of Pearler alphabet.

Pre-Nashville
Before Windows Cleveland was released, there was Windows 95 OSM. In 1996 Microsoft released a build of Windows 95 called build 4.10.999. However it is codenamed Cleveland.

Pre-Seven, "Nashville"
Later, the build is renamed from "Cleveland" to "Nashville". Due to Windows NT 4.0 and development of Windows 98 it is cancelled and original build was merged in order to develop Windows Memphis. The release intended to focus on a tighter integration between Windows and Internet Explorer, in order to better compete with Netscape Navigator. After the deal with Hagsburg(now Kadishenware) it is reset with a Plus pack, an early version of Outlook and a new version of Internet Explorer. Later, the reset build being merged with NT project "Seven" to form Windows Codename: Antarctica.

"Seven"
During development of Windows NT 5.0 Microsoft made a deal with HagsBurg Computers Inc. to collaborate on a NT Project to compete with HagsBurg's competitor Nashan Software Corp., which have already collaborate with Apple Inc. However Bill Gates hated the fact, that Delta OS is open source, which HagsBurg/Kadishenware made, and snap out of It, which to make a variation of NT kernel with key features of Delta OS and Delta DOS kernels, to make a Delta-like NT project (Delta-like means OS behaving in a similar manner to or being compatible to either Delta OS, Delta OS or both).

In late 1996, they created the Windows codename: Seven build 7777.7, which is updated version of Windows 5.0 Beta 1. It introduced logon screen, firewall, new start menu,start screen and Internet Explorer 7.7. It is planned to be released in July 7 1997. Several Seven builds were part of early Windows NT 5.0 builds. However, the project proved to be too ambitious. Later builds featured Delta OS-esque features. They merged reset Windows Nashville from 9x and Windows codename Seven to form Windows Codename: Antarctica in May 1997. Because of bankrupcy caused by the sabotage, Hagsburg is refounded as Kadishenware, but keeps the collarobation with Microsoft.

"Antarctica"
In 1997, Windows Antarctica was formed, and planned to be released in mid 1999. However,due to builds of Windows 2000 (NT 5.0), which EUR edition was released three days before first build of Beta 3), it is updated. Build 1111.1 It introduced Microsoft Office 1999, Microsoft Edge Browser, and Emergency mode. The last build known is build 1200.5.

Pre-Development
The Odyssey document confirms there would be new variantion of Windows 2000 Server. Later, it would given a codename Bloom. However, later documents renamed Bloom to Delta. As stated in confidental document, Delta is originally planned as a Windows 2000 Server variation. This changed in August 5 1999.

Development
Five days after the release of Windows 2000, Windows Antarctica was renamed to Windows Codename Delta by adding Windows 2000 Datacenter features to the Windows NT 5.0 EUR features and Windows Antarctica features. On build 2000.0 there was a debate when is this actual pre-alpha of Windows OMV or post RTM build of Windows 2000 Datacenter Server. However, the only exception of this combined build is the rare boot screen with "Datacenter Server" instead of "Server Family". This means the beta testers and users to not confusing the build with the Server and Advanced Server ones. The "SD" in the build tag refers to a new code management system that Microsoft was developing ("Source Depot"). Build 2004.6 has bug fixes and many security patches, featuring some elements from early Windows Chicago. Build 2009.5 has elements from Plus for Windows 95 and 98, Microsoft Plus! Game Pack: Cards & Puzzles, Microsoft Plus! for Kids!, Windows For Pen Computing 2.0 ,WinG. First appearance of the word "Delta" is in build 2009B.8. In build 2012.8 it introduces startup and shutdown screens. At WinHEC in January 31 2000, Microsoft officially announced and presented an early build of Delta (build 2020.4), focusing on a new modularized architecture, built-in CD burning, fast user switching, and updated versions of the digital media features and other features introduced by ME, also featuring OOBE. Build 2020.9 introduced logoff screen. At build 2072.8 (A.K.A Pre-Developer Release) bootscreen "Microsoft Windows 2000 Datacenter Server" was renamed to "Microsoft Codename: Delta" dropping "Datacenter Server" because this Windows version was special for Kadishenware's "Delta OS" a server OS. At build 2022.9 it introduced white version of Windows Standard theme, later to be known as "Prototype". Build 2042.5 imports features from PocketPC 2000 and WindowsCE 3.0. Build 2051.2 has features from Windows NT 4.0 Terminal Server. Build 2054.6 introduced new startup and shutdown sounds. The startup sound is reversed Windows 2000 build 2000 startup. The shutdown sound is chime assemble with turning and transforming into Windows 98 startup sound, ending with it's RTM shutdown sound.

It keep the start-up and shutdown sounds of previous versions. Build 2062.6 introduced VoiceSearcher.

Tev Hanamadski contiunes development of Neptune and Odyssey, however, puts it on held as he stated they have same features with Codename Delta.

The choice began on September 15 2001 and ended on September 20 2001. There were three choices.

"OMV"
Originally, Windows Delta should named choice of either "Windows.NET" or "Windows 2001" or even "Windows NT 5.5". The most popular choice was Windows.NET. Before Windows OMV was confirmed, Bill Gates think, that none of them will be used, due to changed plan. The plan changed because of the OS was not even fully finished for year 2001, server has not improved and Windows Codename Delta is being different to Windows 2000. Neither does Tev Hanamadski. Before Windows Nashville being developed, Bill Gates went to Vienna while the others were on Greece, everytime when his european car's gas is running out he went to OMV. He states, that OMV is his favorite european petrol station. Many OMV employees worked at Microsoft. This made Tev being confused. Newly reformed company Kadishenware think it is ambitious, choice is logo of OMV or the text itself. Most of employees choosed the logo, since the OS was made with partnership and friendship of Kadishenware and OMV. Tev Hanamadski agreed. The concept of Windows OMV beta was began in September 23 2001. October 3 2001, Windows OMV Beta 2.7 was released, build 2490.1. Beta 2.9 was released in October 10 2001, build 2500.0. Beta 3 was released in October 29 2001, build 2533.8. Final Beta Release was released in November 23 2001, build 2540.4. The last build ever to include the word "Delta" is 2540.0.

Community Technology Preview was release in December 12 2001, build 2557.9. Release Candidate 0 was released in December 13 2001, build 2560.9. Release Candidate 1 was released in December 22,2001,build 2575,9. Release Candidate 2 was released in December 28 2001, build 2590.6.

Trivia

 * So far, Windows OMV is the longest Windows version ever developed. If one counts Windows Nashville, it makes it even longer.
 * It was unknown if there are any reset build of Windows Nashville. Beta-testers believe, that there are some. There are build 4.10.1055 and 4.10.1167. It is unknown if they are real or fake.
 * Before the name is revealed, Beta-testers give a new name for new Windows version. The fan-name is Windows Server 2002. (Coincidentally, Windows OMV is Windows Server 2002, just not the beta testers excepted)
 * It was unknown what build is concept build of Windows OMV. Until 2010, Beta-testers analysed that the concept version of the build is build 2406.8.
 * Windows Powered Family was released during Windows OMV development. The Advanced Server version of Windows Powered share same things as Windows OMV. https://www.youtube.com/watch?v=t-I2tVrClLo. Then Neptune and Odyssey had survived: https://www.youtube.com/watch?v=lui0dQhcsNI, https://www.youtube.com/watch?v=MjeBmQVZWTE. This means that they are successor of Windows OMV.
 * Windows OMV is a sister/brother to Windows 2000 according to either Apple Inc, or due to pre-Development Release.
 * Unlike every other Windows OS since 2003, Windows OMV doesn't have it's normal counterpart, though this is a server OS. It does have desktop editions, but they were used for server works.
 * The features of Windows Powered were added to Windows OMV during development of seventh service pack.
 * The Prototype theme in post-Alpha releases looks identical to Luna from Windows XP, with mixture of Watercolor from Whistler.
