Microsoft Is Now Using AI to Find Bugs Before Patch Tuesday, and Patches Are Getting Bigger

The Verge·medium signal

Microsoft said it is using AI to 'identify potential issues earlier,' which will translate into Windows 11 updates bundling fixes for more security issues per cycle. The framing is a productivity win, but the operational consequence for anyone managing fleets is larger, riskier patch payloads landing on the same monthly cadence. Separately, Ars Technica reports an unresolved Windows Defender 0-day whose patch itself could let attackers fill a target's hard disk — a reminder that AI-accelerated bug discovery does not imply AI-accelerated fix quality.
