Microsoft Security and Non-Security updates for June 2010
This month a large number of important security updates were provided by Microsoft that should be promptly applied. It may not be widely known, but Microsoft will also use Windows Update to schedule highly important non-security updates on the fourth Tuesday of each month. These should also be updated to ensure critical functions work accurately for Windows.

QUOTE: As a number of readers have reported, Microsoft released a few non-security updates on Tuesday via Windows Update/Automatic Updates. Most of our readers will recognize that the 4th Tuesday of the month is when Microsoft usually releases non-security updates. From the results of a couple of computers here in my office, the updates involve the .NET Framework versions 3.x and 2.x. As with all updates, please remember to test the update in your respective environment prior to wholesale deployment. More information on the .NET Framework update available at KB982524.
