Microsoft has blocked the July 2026 Windows 11 security update (KB5101650) for a limited number of Dell PCs after confirming it can cause serious issues on affected devices.
According to Microsoft, some Dell computers with Intel processors may experience:
- Unexpected shutdowns
- Slower performance
- Increased heat
- Faster battery drain
- A yellow warning icon next to the Intel Innovation Platform Framework Processor Participant driver in Device Manager
The problem is linked to a compatibility issue between the Windows update and a Dell Intel driver.
The company says it is working with Dell and expects to release a solution in the coming days.
