Windows Phone 7 One Step Closer To UpdateWindows Phone 7 One Step Closer To Update

Microsoft has pushed out an update to its Zune desktop player that is also the mechanism that will be used to update a Windows Phone 7 device. It doesn't mean the update is imminent, but does give assurance one is coming, and it will be sooner rather than later.About two weeks ago it became clear that a January update wasn't meant to be. Based on the information available at the time, February isn't looking too likely. Nothing in the current update for Zune makes me think the timeline of March or April is changing, but it does mean Microsoft is making progress and an update is likely eight weeks away at most.

Microsoft occasionally pushes out minor updates to allow larger updates to work a few months later. Vista had a number of patches that had to be applied before Service Pack 1 could be installed and those were rolled out about a month or two before the service pack was released. The desktop Zune player has been used for years to update the Zune MP3 players, but never Windows Phone 7. By rolling those patches out now it allows MS to make sure the patches themselves don't cause problems and also allows developers and others in the beta or prerelease program to test both the update and the update mechanism.

WPCentral has been paying close attention to the update. The version number in the Zune About screen doesn't change, staying at 4.7.1404.0, so it would appear this does nothing but allow Windows Phone 7 updates. What is visible if you poke around deep enough is ZuneWmdu.dll and ZuneWmduResources.dll are updated and those two files are known to be necessary for the WP7 update process.

If you have Windows Phone 7 and the Zune desktop software, you don't need to do anything. Windows Update will push the update out along with the security fixes mentioned in the twelve February bulletins that were released on Patch Tuesday, February 8.
