The official list of Windows Update patches was updated over the weekend to show that 34 patches rated "optional" are headed for the Automatic Update chute this Tuesday, April 21. No, it isn't officially a Patch Tuesday. It's not even a Fourth Tuesday. But at least we're getting some advanced notice from Microsoft.

Here's what else I could find out about the expected patches:
