Microsoft is rewriting Windows patch guidance because of AI

Microsoft advises organizations to expedite their Windows update deployment timelines due to advancements in artificial intelligence that allow cyber attackers to quickly exploit vulnerabilities after security updates are released. Jeremy Chapman, Director of Microsoft 365, warns that delaying critical quality updates with security fixes increases the risk of exploitation. Microsoft recommends a quality update deferral period of fewer than three days, update deadlines of zero or one day, and a grace period of no more than two days. The Windows Autopatch report within Microsoft Intune helps identify unpatched devices, allowing administrators to adjust update deferral policies. Organizations can configure update delivery settings through policy controls in Windows Autopatch and Microsoft Intune, as well as other management tools like Microsoft Configuration Manager and Windows Server Update Services. Microsoft also promotes the use of Hotpatch for quicker installation of security updates without rebooting and encourages Conditional Access policies to restrict access to corporate resources for devices that lack required updates.
