Microsoft has changed the codename for the post-Vista version of its upcoming Windows operating system from Blackcomb to Vienna.
Software developers typically use codenames for software projects while allowing the marketing department to come up with a more appropriate name at a later stage.
Windows Vista was developed under the Longhorn codename, while the preceding Windows XP operating system was known as Whistler.
Microsoft disclosed the name change on its Channel 9 website for developers, but did not provide any data on a projected launch date for Vienna.
The next version of Windows remains as Vista, which is scheduled for release later this year.
