Today, May 26, Windows Update tried twice to install “Feature update to Windows 10, version 1803,” but “Failed to install.”
I am surprised that the Feature Update reappeared after it was previously hidden with WuShowHide. I was able to hide it again, though.
Still holding off the forced updates with a metered connection. It is more annoying than previously, as OneDrive now pauses automatic folder syncing due to the metered setting.
