On build 2000.1 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 execption 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. On build 2012.8 it introduces startup and shutdown screens.

"OMV"
Originally, Windows Delta shoud named choice of eitner "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. Rosie Inc. being confused. The founder 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 patnership and friendship of Rosie Inc. and OMV.
