Microsoft blocks the July Windows 11 update on some Dell PCs

Microsoft has blocked the installation of the July security update for Windows 11 on some Dell computers. The move was prompted by problems that arise after it is installed.

According to the company, affected devices shut down unexpectedly after the update and also see a drop in system performance. To prevent further failures, Microsoft has temporarily paused the automatic delivery of the update to these PC models.

The company has not specified exactly how many Dell devices are affected by the issue or what stage the fix is at. Until a corrected version of the update is released, it will not be offered to users of the computers in question.

The case is yet another example of how Windows' monthly security updates can cause side effects on certain hardware configurations, forcing Microsoft to restrict their rollout on a case-by-case basis.
