The Inquirer has been looking at the latest release of Microsoft’s Vista operating system. This time, we tackle build 5744, otherwise known as Release Candidate 2. Tested today is the x64 version, which has a date stamp of 03/10/06. So what has changed over RC1 and earlier builds? Elsewhere, Microsoft has said they expect Vista’s deployment rate to be twice that of Windows XP. Finally, even though RC2 will be the last public test build, Microsoft still has changes up its sleeve for Vista RTM.
