Today the Microsoft Security Response Center (MSRC) posted details about the April security updates. On Tuesday, April 12 at approximately 10 AM Pacific Time Microsoft will release 17 bulletins, 9 critical. 

The easiest way to get the updates when they're available is to turn on Windows automatic updating. For more information about how this works, see Understanding Windows automatic updating.

The Microsoft Security Bulletin Advance Notification Service offers details about security updates approximately three business days before they are released. We do this to allow customers (especially IT professionals) to plan for effective deployment of security updates.

Advanced Notification includes information about:

  • The number of new security updates being released
  • The software affected
  • Severity levels of vulnerabilities
  • Information about any detection tools relevant to the updates

For more information about the security updates that will be released on April 12, see Microsoft Security Bulletin Advance Notification for April 2011.
