Known issues in this update


Symptom Workaround
Devices using a manual or auto-configured proxy, especially with a virtual private network (VPN), might show limited or no internet connection status in the Network Connectivity Status Indicator (NCSI) in the notification area. This might happen when connected to or disconnected from a VPN or after changing the state between the two. Devices with this issue might also have issues reaching the internet using applications that use WinHTTP or WinInet. Examples of apps that might be affected on devices in this state include, but are not limited to, Microsoft Teams, Microsoft Office, Microsoft Office 365, Microsoft Outlook, Internet Explorer 11, and some versions of Microsoft Edge.

This issue is resolved in KB4554364.

Because of a bug, some customers who purchase a Windows 10 Pro Education device, may receive a genuine edition of Windows 10 Education.

Windows 10 editions for education customers, Windows 10 Pro Education builds on the commercial version of Windows 10 Pro, and Windows 10 Education builds on Windows 10 Enterprise. This bug is not expected to introduce any negative experiences for customers.

A resolution for this issue will be released in a future servicing update that will prevent customers from entering this state.
After installing this update on a Windows 10 device with a wireless wide area network (WWAN) LTE modem, reaching the internet might not be possible. However, the Network Connectivity Status Indicator (NCSI) in the notification area might still indicate that you are connected to the internet. We are working on a resolution and will provide an update in an upcoming release.
