BSOD and Other Issues

  • Resolved an issue wherein enabling the speech recognition causes the User Account Control window to appear unexpectedly.
  • Addresses a bug that previously fails to notify the target application when you select the Copy link command on the Share menu.

Shortcut Keys & IME Errors

  • Resolves an anomaly that causes the upload of diagnostic logs to a management service, such as Microsoft Intune, to fail. This failure occurs because of a network time-out on a slow network.
  • Upon entering an MDM service as the administrator, there appears a notification to all the users. This bug usually occurs when using Microsoft Intune to find the location of a managed device.
  • Earlier, deploying Microsoft Endpoint Configuration Manager will stop the error if the AppLocker software is enabled on the device.

Virtual Networks and Azure Account Fixes

  • Previously, using a Volume Shadow Copy Service (VSS) snapshot will trigger the virtual machines (VM) containing the Resilient File System (ReFS) volumes. This, in turn, causes the VSS snapshot to fail with a time-out and prevents access to the ReFS volume for at least 30 minutes.
