Microsoft today took the unprecedented step of postponing an entire month's slate of security updates for Windows and its other products just hours before the patches were to begin rolling out to customers.
"We discovered a last-minute issue that could impact some customers and was not resolved in time for our planned updates today," Microsoft said in a post to the MSRC (Microsoft Security Research Center) blog. "After considering all options, we made the decision to delay this month's updates."
Today was set as Patch Tuesday, the monthly release of security fixes from Microsoft. Normally, Microsoft issues the updates around 10 a.m. PT (1 p.m. ET). Although Microsoft did not time stamp its blog post, the SAN Institute's Internet Storm Center (ISC) pointed out the delay at 8:22 a.m. PT (11:22 ET).
