It’s the third week of the month — the week we find out whether Microsoft acknowledges any side effects it’s investigating as part of the monthly patch-release process.
First, a bit of background. Microsoft has released patches for years. But they haven’t always been released on a schedule. In the early days, Microsoft would release updates any day of the week. Then in October 2003, Microsoft formalized the release of normal security updates on the second Tuesday of the month. Thus was born Patch Tuesday. (Note: depending on where you are in the world, Patch Tuesday may be a Patch Wednesday.) The following day, or in some cases, over the next week, users and admins report issues with updates — and Microsoft finally acknowledges that, yes, there are issues.
