Microsoft has confirmed that it has blocked the availability of the recent Windows 11 July Patch Tuesday update (KB5101650) on Dell PCs, after Dell reported a number of issues including unexpected shutdowns, overheating, poor performance, and more caused by the preview update that released before it.
The KB5101650 began rolling out on July 14, and includes a number of quality of life improvements and fixes. For most users, this update is issue free, but Dell PCs will find that the update is not available for them currently.
