Windows Live Messenger 2011 Build 15.4.3508.1109 is now being served through Microsoft Update, the company informed. This means that customers running the original release of Windows Live Messenger 2011 on top of Windows Vista or Windows 7 will be upgraded to Build 15.4.3508.1109.

However, this will only happen if they turned Microsoft Update on, as Build 15.4.3508.1109 is nothing more than an optional update for the latest iteration of the software giant’s instant messaging client.

Microsoft has a Knowledge Base article available explaining just how to turn on MU in order to receive any optional updates that might be available for the software they have already installed.

According to the software giant, users still running Windows Live Messenger 2011 Build 15.4.3502.0922 should make sure to make the jump to Build 15.4.3508.1109 as soon as possible.

The latest release of the IM client is what the company refers to as a QFE (Quick Fix Engineering).

In fact, Build 15.4.3508.1109 is QFE1 for Windows Live Messenger 2011. And in this regard, some Messenger 2011 users might remember the fact that Windows Live Messenger 2011 Build 15.4.3508.1109 QFE1 was released initially in 2010.

At that time, the Redmond company allowed customers to manually download and install QFE1, but now they can simply have it served automatically to them through MU.

“In Messenger, we fixed a couple of issues where in some cases you could not re-establish video calls or file sharing activities after losing your network connection,” revealed Arthur de Haan, Vice President, Windows Live Test and Systems Engineering.

“Also, sometimes your status messages and display picture were not synchronizing correctly between PCs, so you’d see a notification that changes made would not be seen on other computers. We also made various performance and stability improvements.
