The WSUS Team announces that the Windows Update Agent (WUA), commonly known as the "WSUS Client" will see an update starting some time around the end of July. When WSUS clients attempt to contact WSUS servers or Microsoft's equivalent Microsoft Update servers, they always check to see if there are self-updates ready for deployment.

Depending on how you've configured your download and installation settings via Group Policy, the client may self-update before your usual scheduled time. Or, it may occur as part of your regularly scheduled updates. More information on how your settings impact when you'll see the upgrade can be found at the WSUS Team blog here.

What can you expect from the new update? No changes in the user interfaces, but some improvements to its core engine. From the WSUS Team Blog:

So what are we doing this time? Well, this particular update won't really change the way the client looks or feels to you, but you may notice some improvements in the length of time it takes Windows Update to scan for updates and how quickly you'll receive signature updates. For example, in this update, we've invested heavily in reducing the amount of time it takes the Windows Update agent to scan to see if new updates are available. In this case, we've seen some instances of the scan times on some machines decreasing almost 20 percent.
