Windows 10 KB4554364 Update Fixes Internet Connectivity Issues

Microsoft has released an out-of-band Windows 10 update to fix a bug that was causing internet connectivity issues on devices with proxies, including virtual private networks (VPNs).

Earlier this week, Microsoft stated that there was a bug in Windows 10 that was causing popular apps such as Microsoft Teams, Microsoft Office, Office 365, and Outlook to not be able to connect to the Internet if using a VPN.

“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 or disconnected to a VPN or after changing 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 are as follows but not limited to Microsoft Teams, Microsoft Office, Office365, Outlook, Internet Explorer 11, and some version of Microsoft Edge.”

Today, Microsoft released the out-of-band (OOB) Windows 10 update titled ‘ 2020-03 Cumulative Update for Windows 10 Version 1909 for x86-based Systems (KB4554364)’ that resolves this issue.

“Addresses an issue that might display a limited or no internet connection status in the notification area on devices that use a manual or auto-configured proxy, especially with a virtual private network (VPN). Additionally, this issue might prevent some devices from connecting to the internet using applications that use WinHTTP or WinINet,”

Microsoft suggests that you only install this update if you are affected by this issue.

This OOB update is not being offered using Windows Update and must be installed manually from the Microsoft Catalog.

For instructions on how to install this update for your operating system, see the KB for your OS listed below, all of which were released March 30, 2020:
