Microsoft has released an out-of-band update, KB5121767, to resolve an incompatibility issue affecting certain Dell models, allowing them to receive the July 2026 Windows security patch.

A separate hotpatch, KB5121768, is available for eligible Windows 11 Enterprise devices. Microsoft paused the Patch Tuesday rollout for the affected models to facilitate this update.

The 200GB catch hiding in Windows 11’s new recovery feature

Microsoft has introduced point-in-time restore for Windows 11 users, enhancing the traditional System Restore. This new recovery tool allows users to recover their PCs from software issues, problematic drivers, or faulty updates, even when Windows won’t boot. It uses the Volume Shadow Copy Service (VSS) to automatically generate restore points every 24 hours, which include both system and user files, unlike System Restore. Point-in-time restore manages storage by deleting restore points after 72 hours and integrates seamlessly into Windows Settings, being activated by default for volumes over 200GB. Users with smaller volumes must activate it manually. It also incorporates Reserved Storage to ensure restore points do not consume regular disk space. The feature is available on Windows 11 Home and Pro editions with the installation of the optional Preview Update KB5095093. Users can access point-in-time restore through Windows Settings under System > Recovery, and initiate recovery via the Windows Recovery Environment (Windows RE).
