I'm seeing reports that Microsoft is getting pushy trying to get folks off of Win10 version 1803.For example, Terry Muench on AskWoody says:Thank you Microsoft for force-feeding me W10 v1903.
I have been blocking it (first v1809) for months using WUShowHide.
On Sat 10/19/2019 I got the DREADED (We&re here to help you) UpdateAssistant popup giving me a few minutes to save my work before starting the Upgrade.
Fortunately I was able to Cancel.
I checked the #4 UpdateAssistant Tasks in Task Scheduler — which I had Disabled — and Microsoft had re-Enabled them.
I Disabled them AGAIN and thought I was set.
