Microsoft has released an optional update that should resolve a recent connectivity issue. The problem appeared to be rooted in Windows 10's proxy handling, with users utilizing a VPN or proxy experiencing connection loss even when they switched it off.
The bug additionally led to the inability for some applications to use WinHTTP and WinINet, which rendered Halo: The Masterchief Collection and Bleeding Edge players unable to connect.
“An out-of-band optional update is now available on the Microsoft Update Catalog to address a known issue whereby devices using a proxy, especially those using a virtual private network (VPN), might show limited or no internet connection status,” said Microsoft in its documentation.
However, it's still recommended that you don't install this update unless you're actually experiencing options. Due to the severe hampering of productivity, Microsoft has been forced to rush out a patch, and that could mean other unexpected problems. There are currently no known issues with the patch, but you never know.
Microsoft recommends you install the latest service stack update (SSU) before this fix to further avoid issues. You can then grab the optional update by heading to the Windows Update > Optional Updates Available > KB4554364.
Considering the global pandemic, the company has been quick to react to this problem. This fix rolled out before its planned window of early April, which is always a pleasant surprise. You can install it on Windows 1909, 1903, 1809, 1803, and even 1709, thanks to its revised end of service date. If you can't download the update due to the connection issues, Microsoft says restarting your device should temporarily mitigate the problem.
