Microsoft has released an update for Windows Live Essentials 2011. The announcement was made by Steven Abrahams, Lead Program Manager – Windows Live.
“Today, we released an update for Windows Live Essentials 2011 in all 48 languages. This minor release includes numerous updates across all of the programs in the Essential package, including Windows Live Messenger, Mail, Photo Gallery, Movie Maker, Family Safety, Writer, and Mesh. In the coming weeks, customers on Windows Vista SP2 and Windows 7 will receive a notification prompting them to upgrade to the new version. Since this release contains critical fixes for the Essentials package, in a few months, the update will become required for all eligible customers.”
I earlier had version 2011 (Build 15.4.3538.0513) and this has now been updated to Build 15.4.3555.308.

The detailed change log has not been posted yet - but it says that the release includes critical fixes. If I can guess, the updates can be to ensure compatibility with Windows 8 & Internet Explorer 10. We will update this post when the change log or what has been updated are made known.
Because it has critical fixes, this update will be mandatory in a few months for all Windows Live Essentials users.
One can download the update from the Windows Live Essentials website. or from the Download Center. You can also get its English stand-alone installer here.
UPDATE 1 : There were some reports that after this update Mesh is causing unnecessary File transfer. Some Additional Details on Windows Live Mesh provided by Windows Live Mesh Team:-
Yesterday we released an update to Mesh in response to feedback we’ve received from many of our customers. This update addresses many of their top issues – particularly those resulting in a crash or trouble syncing certain files. A side effect of this update is it causes Mesh to rebuild its index of what files need to be synced and where. As a result, it takes a bit of time for this process to happen.
For most users this process takes just a few minutes. But if you sync many GBs of data, this process can take upwards of several hours. Before the index has been rebuilt, Mesh will start to re-sync your files across computers. Once the index has been rebuilt on each computer, Mesh will realize that your files are already present at which point subsequent file downloads/uploads will stop. Then Mesh’s status will appear as “up to date”.
No action on the user’s part is required for this process to complete. It just takes time and patience. If this does not auto-resolve after one day (for extreme cases) please let us know. We apologize for the inconvenience or concern this has caused some customers. We genuinely care about your experience with our product and will continue to monitor the forum for additional issues.
UPDATE 2: This update improves performance in Windows Live Essentials 2011.
The following list describes these changes:
- Setup: During installation, the splash screen loads faster after user accepts UAC prompt.
- Windows Live Mail: When users click on photos within Windows Live Mail that are hosted on SkyDrive or Facebook, instead of using the Client
- Album Viewer to view the photos, a browser opens the web album viewer for that application.
- Windows Live Messenger: Fixes the Messenger sign-in error “0x84cb000c” and the Messenger crash or hang when accepting/declining a pending invitation. When users click on photos are hosted on SkyDrive or Facebook, instead of using the Client Album Viewer to view the photos, a browser opens the web album viewer for that application.
- Windows Live Movie Maker: Fixes error “80004003” where Windows Live Movie Maker can’t open project files. Fixes setup failure error “80040705” and error “87260103” or when Movie Maker becomes unresponsive, hangs when adding WMV video files.
- Windows Photo Gallery: Microsoft updated authorization method required to publish to Flickr and Facebook. Microsoft updated authorization method to communicate with Bing Maps services for geo tagging.
This update will upgrade customers with Windows Live Essentials 2009 Vista sp2 and higher to Windows Live Essentials 2011.
Note: Customers with Windows Live 2009 XP are not impacted.
The initial update will be optional for a short time, after that initial offering, the update will be required which means the update will need to be installed to continue using Windows Live Essentials applications.
For the optional update, you can ignore the dialog and continue using any currently running Windows Live Essentials applications; these applications will not be blocked by the update.
For the mandatory update, Windows Live Essentials users will be required to update their current versions. Canceling the update request will continue to block the applications from launching, but running applications will not be blocked.
