Improvements and fixes
This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:
-
Addresses an issue that may prevent a VPN connection from establishing for some users that are using VPN with IKEv2. The connection fails with the error, “Remote Access Error 809.”
-
Addresses a Microsoft Intune issue that occurs after installing any of the updates released between July 24, 2018 and September 11, 2018. Windows no longer recognizes the Personal Information exchange (PFX) certificate that’s used for authenticating to a Wi-Fi or VPN connection. As a result, Microsoft Intune takes a long time to deliver user profiles because it doesn’t recognize that the required certificate is on the device.
If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
