Answer 1

Please stop pushing updates on me!  I am tired of them. I like the way Windows runs right now...I am not a Luddite, I just don't want the any more wonkyness or weird Chromium hybrid crapshoots.  Please, let me be!  In seven days, I don't want to have this argument again!  If I have to, I'll look for legal means....please just stop!!!

WHO IS RESPONSIBLE IF I CAN'T WORK TODAY?

Answer 3

Hi Carl,

This is an optional D release update. To summarize, this update is the preview of the March Patch. No need to install unless you are looking for a fix specifically in the release notes.

Please read the following on about the update servicing here:

Windows 10 update servicing cadence

https://techcommunity.microsoft.com/t5/windows-it-pro-blog/windows-10-update-servicing-cadence/ba-p/222376

The***“C” and “D” releases***occur the third and fourth weeks of the month, respectively. These preview releases contain only non-security updates, and are intended to provide visibility and testing of the planned non-security fixes targeted for the next month’s Update Tuesday release. These updates are then shipped as part of the following month’s “B” or Update Tuesday release.
