Affected devices will have more than one Always On, Always Connected capable network adapter, such as the Microsoft Surface Pro 7 and Microsoft Surface Laptop 3, and might receive errors or unexpected shutdown or restart.

To safeguard your update experience, we have applied a compatibility hold on Windows 10 devices with affected drivers or firmware from being offered Windows 10, version 2004.

After using the Deployment Image Servicing and Management (DISM.exe) command /restorehealth to detect and correct system corruption, you might receive a report from the tool that corruption is still present. This can occur even when it has been repaired. An example for using the /restorehealth command is: DISM.exe /Online /Cleanup-image /Restorehealth

Workaround: If you receive reports that there is still corruption, subsequent scans should indicate the true state of the corruption. You can verify that DISM has fixed it by rerunning the same command or by using the /ScanHealth command. An example using the /ScanHealth command is: DISM.exe /Online /Cleanup-Image /ScanHealth

Next steps: We are working on a resolution and estimate a solution will be available in mid-June.
