Animated cursor patch may break audio

I made my son do the right thing and promptly update his notebook PC as soon as the patch for the ANI animated cursor vulnerability appeared. The next day, he complained that his amplified speakers had stopped working.

The internal speakers were fine, so we tried plugging in a pair of headphones instead - still no joy. My initial reaction was that the sound jack had probably broken, and he'd have to take it in for a technician to check it.

Then I remembered that I'd written briefly about a hotfix issued by Microsoft to restore compatibility between the GDI patch that fixed the animated cursor vulnerability and software for the Realtek audio chip.

Did the notebook have Realtek hardware? Yes!

After a few minutes to download and install the patch and reboot the system, my domestic status as an IT guru was restored.

The incident left me wondering about two things.

How many technicians are making hay out of this issue? Onboard Realtek audio hardware seem pretty common among the notebooks and desktop motherboards I've used recently, and the fact that the sound didn't fail completely makes a socket problem a likely candidate.

How hard would it have been for Microsoft to arrange for the hotfix to be automatically downloaded and installed by Windows Update if it detected relevant Realtek hardware?
