In a few days (5/5/09), Windows 7 Release Candidate will be publicly avaliable for download.
In the mean time, Microsoft released an 11 minutes video describing Windows 7 RC features and improvements from the beta.
The video talks about the new User Account Control (UAC) improvements, new Winkey shortcuts, Jumplists and application integration with Jumplists (like Live Messenger, Office products, Windows Media Player… ), Themes and…. a new virtualization technology – Virtual Windows XP Mode.
Virtual Windows XP Mode is a new separate install feature (at the moment…) which gives you a full Windows XP environment running as a virtual machine on your Windows 7. This feature enables you to launch the applications you install in the Virtual Windows XP on your Windows 7 desktop. For example, you can run both Internet Explorer 8 (which is built-in in Windows 7) and Internet Explorer 6 (which is built-in in Virtual Windows XP) or Office 2007 and Office 2003.
More about Virtual Windows XP Mode soon…
The video can be download from Microsoft Download Site.
