Fortunately, even this once-a-month annoyance is ending.
Starting with Windows 10, updates install much more regularly than on Patch Tuesday, and usually with much less trouble.

Testing all possible computers systems would be impossible. But that doesn't mean that the update had any sort of issue in and of itself.
Probably because it wasn't Microsoft's fault. Over one billion computers run Windows in the world.

Unfortunately, there are an infinite number of hardware and software configurations that could exist on a Windows computer. True, your computer suffered some ill effect due to the updating.
