Windows Codename Eveserv.

Windows Breeno (Codenamed Heelabout) was released by Microsoft in early 2010 for Home Server users. Technical support ended 12th September 2015, Long Term Support will be ends 10th January 2020.

Long developer madness - 2001 - 2006
In PDC 2002, CEO of Microsoft Steve Ballmer said: 'You have XP, you have 2000 Server. Wanna for home users? If yes, then you'll be the one of our new operating systems, user-friendly. Introducing Windows XP Home Server codenamed Heelabout'. Actually 2 builds were made before PDC 2002 conference. In PDC 2003 Bill Gates mentioned 'Heelabout' with release date - 2nd September 2004. The build presented here was 3341.pdc03.030321-1451 with Longhorn Plex theme and very early 'Customize Your Home Server', which was specially made for PDC 2003 Presentation. Simillar build exists, but it's 3 days earlier compiled than that. In 2004 there was no mention about that project until PDC 2005, where CEO said: 'We haven't said about "Heelabout", and it's official name will be Breeno, and it will be released as soon as we say it's finished, so we think it will be year 2007 or so', then another build presentation was shown, it ws build 5420.winmain.050411-1105 and somehow the video from it was cut, so we can't see what happened, but Paul, the recorder of that video said: 'It was like Longhorn in 2003, but somehow my Camera stopped working, so i stopped recording and listened', thus some mockups were done by amazing people. In 2006 Microsoft started new website 'breeno.microsoft.com', and it was the page for Windows Breeno.

Extremely short, but worth it? - 2007-2009 - Beta 2 and RTM
In 2007, the website got down for 3 months for Server 2008, but it got down instantly and host was down for 2 next month. After that website got back. Nothing really interesting about it in PDC 2007,2008 and 2009, but there was no Aero theme, but original 'Chrome' theme for it.

Trivia
-It got update later to be renamed to 'Windows Home Server'

-It is only Windows OS to be have very long development cycle.
