Why is it that after each and every Windows update there is a slew of articles on how to fix what the update broke?! Doesn’t Microsoft test the updates before releasing them into the wild?

And please, do not bring up that old, worn-out bromide that “Windows has the largest attack surface”. IF the O/S was written with security in mind rather than the ease of data harvesting, the success rate of the cyber attacks would be much lower.

One example of a security vulnerability is/are programs running in user space having access to system/administrative space. If user space was walled off from system space (as is done in *nix O/Ss) there would be no need for UAC and other “security” measures incorporated into Windows by Microsoft over the years.
