It didn't happen to me
Ran the updates the other night. For whatever reason, KB3146449 wasn't installed on my machine.
However, KB3035583 was included in the list of "Important Updates" again FOR THE FIFTH TIME.
I keep unchecking it and hiding it. It keeps coming back like pernicious cancer.
Here's my compiled list of unwanted WX and telemetry "updates" which I keep an eye out for. You can put these in a batch file and run as Administrator:
wusa /uninstall /kb:2952664 /norestart
wusa /uninstall /kb:2976978 /norestart
wusa /uninstall /kb:3022345 /norestart
wusa /uninstall /kb:3035583 /norestart
wusa /uninstall /kb:3068708 /norestart
wusa /uninstall /kb:3075249 /norestart
wusa /uninstall /kb:3080149 /norestart
wusa /uninstall /kb:3146449 /norestart
I have W7, so there are actually several more which W8it users should worry about. Once you run the batch, reboot, then launch WU, Search for updates, and manually hide each of the KBs which come back. That'll keep them at bay until microcrap sends the secret signal to unhide them again, heh.
