As a consequence of their recent effort to boost the numbers of Windows 10 installs using any means possible, however questionable, and turn their paying customers into beta testers, Microsoft have been especially hostile to their users as of late, installing nag-screens and “telemetry” code (also known as “spyware”) under the guise of important updates to existing installs of previous versions of Windows. While I would happily eschew Windows for Linux on all the machines I use, and have largely done so, the idea of avoiding Windows in totality is, sadly, not yet practical―the common-use machines I maintain in our lab required it for various reasons, and even I still keep a Wintendo partition.
There are plenty of discussions around about what to do about this. Here's a fine example. Though this is intended for my own reference, I've had success with the following:
wusa /uninstall /kb:2952664 /norestart /quiet
wusa /uninstall /kb:2976978 /norestart /quiet
wusa /uninstall /kb:2977759 /norestart /quiet
wusa /uninstall /kb:2990214 /norestart /quiet
wusa /uninstall /kb:3021917 /norestart /quiet
wusa /uninstall /kb:3022345 /norestart /quiet
wusa /uninstall /kb:3035583 /norestart /quiet
wusa /uninstall /kb:3044374 /norestart /quiet
wusa /uninstall /kb:3068708 /norestart /quiet
wusa /uninstall /kb:3075249 /norestart /quiet
wusa /uninstall /kb:3080149 /norestart /quiet
wusa /uninstall /kb:3123862 /norestart /quiet
pause
Copy/paste that into a .bat file and run it as the administrator. Next time you run Windows update, these updates might reappear in the pending update list—right click on them and hide them.
Of course, it's proprietary software—there's only so much you can do before you simply have to trust the vendor.
