This update targets the Intel Innovation Platform Framework drive, which caused performance, power consumption, and system behavior issues. It is applicable for Windows 11 versions 25H2 and 24H2. A separate hotpatch, KB5121768, is available for eligible Windows 11 Enterprise devices. Microsoft paused the Patch Tuesday rollout for the affected models to facilitate this update.
