Microsoft has officially released Windows 11 KB5121767, an out-of-band (OOB) cumulative update for Windows 11 versions 24H2 and 25H2. The emergency release resolves a compatibility issue that forced the company to temporarily block the July 2026 Patch Tuesday update (KB5101650) for a limited number of Dell PCs equipped with Intel Innovation Platform Framework (Intel IPF) drivers.
Earlier this week, Microsoft paused the rollout of KB5101650 on affected Dell systems after identifying an incompatibility that could lead to abnormal performance, increased power consumption, and unexpected system behavior.
