After Vista, the next Windows client, codenamed “Vienna”, will be the 7th version of Windows shipped by Microsoft, which has more recently been renamed to Windows Seven or Windows 7, targeted to release after 2 or 2 and a half years after Windows Vista, which is year 2009 or 2010.
For more information on Windows Seven, the next version of Windows, check out these:
Based on the these sources, Windows Seven will not a major release, like Vista, but will be somewhat like an update of Vista, with the following version, a major release, released 2 years after.
Some features that are mentioned would be the inclusion of the Ribbon user interface of Office 2007, better mobile connectivity capabilities, “Intelisense” typing features (something like auto-complete, maybe based upon Windows Powershell).
One thing I noticed is that not all the information in these sources are consistent, where Paul Thurrott’s FAQ states that Windows Seven will ship in only 64-bit, as part of Microsoft’s x64 migration schedule, but in the more recent post on ZDNet, it mentioned that it will be released in both 32-bit and 64-bit.
On which one is correct, I have no idea, but since Windows Server 2008 (codenamed Longhorn), will be the last Windows Server to have support for both 32-bit and 64-bit, it its quite possible that Windows Seven will be 64-bit only, but according to this, Microsoft themselves have no decided yet.
Definitely looking forward to more news on Windows Seven!
