This update includes the following improvements:

New! We provided the ability for you to consent to receive urgent notifications when focus assist is on.

New! We restored functionality for Windows Autopilot deployment scenarios that are affected by the security mitigation for hardware reuse. This update removed the one-time use restriction for self-deploying mode (SDM) and pre-provisioning (PP). This update also re-enabled any User Principal Name (UPN) display in user-driven mode (UDM) deployments for approved manufacturers.

We reduced the overhead of resource contention in high input/output operations per second (IOPS) scenarios that have many threads contending on a single file.

We improved the reliability of a push-button reset after an OS upgrade.

We fixed an issue that makes the tenant restrictions event logging channel inaccessible if you remove the EN-US language pack.

We fixed an issue that prevents troubleshooters from opening.

We updated the Remove-Item cmdlet to properly interact with Microsoft OneDrive folders.

We fixed an issue that causes certain docking stations to lose internet connectivity when waking from Sleep mode.

We added functionality that caches additional audio endpoint information to improve the OS upgrade experience.
