Microsoft have released a build both for Windows Vista and Longhorn Server to testers. Both have build number 5270.
The downlaods are only available to registered testers via the Microsoft Connect website where testerds can download Vista client x86 and x64, Longhorn Server x86 and x64 and Longhorn Server Code x86 and x64.
The Server Beta continues to be unavailable via public channels such as MSDN and TechNet and Microsoft attempts to get feedback from hardware vendors, system builders and software vendors and developers.
This release has focussed on better security, performance and reliability. Included in the release is an updated version of Windows Defender (previously Windows Antispyware) which is more consumer focussed with an updated UI. The firewall also now has bidirectional support and filtering.
IE has better phishing checks based on a users language and there's now the ability for administrators to control the use of external storage devices such as USB Flash Drives.
BitLocker Drive Encryption has been included to protect data on computers when they have been lost or stolen and is designed to work with a Trusted Platform Module (TPM) chip.
Parental controls have been added, which allow parents to limit such things as time at the computer and the websites that can be visited.
Finally the Aqua, sorry Aero interface has been overhauled with the inclusion of transparent glass windows, smoother transitions and a redesigned start menu.
