After installing this update, there may be issues using the Preboot Execution Environment (PXE) to start a device from a Windows Deployment Services (WDS) server configured to use Variable Window Extension.

Some customers report that KB4494441 installed twice on their device. In certain situations, installing an update requires multiple download and restart steps. If two intermediate steps of the installation complete successfully, the View your Update history page will report that installation completed successfully twice. |
No action is required on your part. The update installation may take longer and may require more than one restart, but will install successfully after all intermediate installation steps have completed. We are working on improving this update experience to ensure the Update history correctly reflects the installation of the latest cumulative update (LCU). |
|
After installing the May 14, 2019 update, some gov.uk websites that don’t support HTTP Strict Transport Security (HSTS) may not be accessible through Internet Explorer 11 or Microsoft Edge. |
This issue is resolved in KB4505056. |
