Microsoft has blocked the Windows 11 July 2026 update (KB5101650) on certain Dell PCs due to issues causing unexpected shutdowns, diminished performance, excessive heat, and battery drain. The problems are linked to the Intel Innovation Platform Framework Processor Participant driver, which affects power management. The complications stem from an optional June 2026 update (KB5095093) that introduced changes impacting the performance of some Dell PCs. Microsoft has not provided a list of affected models but is working with Dell to resolve the issue. The July update has been preemptively blocked from installation on incompatible devices, and a resolution is expected soon.
