Windows 10 May 2019 Update recently had a patch issued to repair problems with game audio, and also at time of its release, we noted that everybody wondered what it really might break - and now (sadly) we have our answer: printers, in some instances.

This really is according to user reports on Microsoft's Answers.com site, and also a thread on Google's Chrome Help forum (oddly enough) as spotted by Windows Latest, along with more complaints via Ask Woody.

The issue is the cumulative update KB4517211, which fixed a number of problems including muffled game audio, is seemingly causing major problems mainly for HP printers, but potentially with other brands too.

The Answers.com post notes: "The Cumulative Update for Windows 10 Version 1903 [Windows 10 May 2019 Update] KB4517211 is causing the printer spooler service to stop and also the installed printer is not recognized. It's an HP Officejet Pro 8210 printer.

"When I go into services.msc I can start the spooler and my printer then reappears but because soon as I attempt to print the spooler service stops. If I uninstall update KB4517211, my printer again works."

A number of users then chime in struggling with similar printer-breaking issues, all of them seemingly running HP models.

However, in the Ask Woody thread, GBorn - who blogged about this issue on Born's Tech and Windows World - noted that he'd sought and received feedback from his readers to determine if this is an issue which is specific to HP printers.

However, other medication is reportedly being hit by problems caused by the KB4517211 patch that is interfering with PDF printer drivers and Kyocera network printers. So it would seem that this gremlin isn't only being encountered by HP printer users - but they certainly seem to be the majority of those affected.

The road to reputational ruin?

Once we recently observed, Microsoft is having an entire nightmare here - a potentially very expensive one in terms of its reputation - cheap another fix has seemingly caused yet another bug just pours more fuel around the fire.

There has been a clattering 'domino effect' of bug fixes causing yet more bugs in recent times, with an initial patch to solve some long-standing minor bugs introducing a brand new trouble with Cortana and CPU usage.

Then the treatment for that broke the beginning menu and Taskbar, as well as causing the aforementioned audio issues in certain games - and today the fix for the latter appears to have ushered during these serious printer gremlins.

'Oh dear' doesn't quite pay for it.
