Microsoft has released MED-V 1.0 SP1 and App-V 4.6. The big update to MED-V is full support for 32-bit & 64-bit Windows 7 hosts, but it also includes support for Japanese versions of Windows. Chances to App-V are mostly centered around language support. MED-V is an enterprise desktop virtualization management system that allows administrators to deploy and control Windows XP or Windows 2000 deployments running inside Windows 7 or Windows Vista host operating systems.

For all five of our readers with a Zune HD, you’ll be happy to know the Zune 4.5 firmware was released last week. It features an new Smart DJ mix with personalized recommendations, Zune Marketplace for TV, and better video codec support. Microsoft will also be releasing a new Zune HD 64GB model soon. To get the update, plug it in and sync with the Zune software on your desktop.

For all five of our readers running Windows Server on Itanium processors, you’ll be disappointed to know that after Windows Server 2008 R2, Microsoft will no longer be releasing versions for Itanium processors, and will focus on the x64 platform going forward. There was no 2008 R2 version released for 32-bit processors, either. Microsoft will no longer develop other software for Itanium, and SQL Server 2008 R2 and Visual Studio 2010 are also the last versions to support it. Mainstream support for Windows Server 2008 for Itanium-Based Systems (and R2) will end, in accordance with that policy, on July 9, 2013, while extended support will continue until July 10, 2018.  That’s roughly eight more years of support.

Just so that our entire update isn’t focused on Microsoft today… If you’ve been living under a rock since last week, we just wanted to remind you that the iPad came out on Saturday. It’s magical, especially when you watch Harry Potter on it.

Microsoft has released, through the PowerPoint Team Blog, a new video and some details about some of the updates PowerPoint 2010 will be receiving. The team says this will be the biggest visual update to the product in the last 10 years. PowerPoint’s graphics engine has been rebuilt to take advantage of 3D accelerated graphics cards by using DirectX. Through hardware acceleration, they’re able to add new transition and animation effects. They’ve also added a new timelines UI, animations choreography and painter.

Another feature which was highlighted last week, is a new Protected View, which allows PowerPoint and other Office applications to run in a sandbox when downloading and opening presentations from the Internet. This allows potential malicious code to be isolated and contained within the file. More information on that feature can be found over at the Office 2010 Engineering Blog.

“It is an exciting time for the MacBU with updates to our current products and the first public announcement about the next version of Office for Mac. For several years we have focused on providing the best Microsoft Exchange client for the Mac, and the Web Services Edition delivers that today for Entourage users,” said Eric Wilfrid, general manager for the Mac Business Unit at Microsoft.

While Office for Mac builds on the work done with Entourage 2008 Web Services Edition, Microsoft says it’s more than just a name change. With full support for Exchange synchronization, Office for Mac will also deliver significant changes to better interface with Mac OS X including a new high-speed file-based database with support Time Machine and Spotlight and fully Cocoa based programming.
