For those on Windows 10 May 2019 Update (1903), Microsoft just pushed out KB4517289, taking the OS to build 18362.418.

This Patch Tuesday cumulative update for Windows 10 featured updates to improve security when using Internet Explorer and Microsoft Edge, updates for verifying user names and passwords and updates for storing and managing files.

On October 3rd, Microsoft released a patch for Windows 10 version 1903, which intended to fix a “Print spooler issue” that arose in the May 2019 Update- Windows 10 version 1909. Instead, the update turned out to be detrimental to the print spooler- which was functioning OK for most users beforehand. Thankfully, users have since reported that the issue been appropriately addressed in the latest Patch Tuesday update.

Unfortunately, Microsoft doesn’t consider the ongoing Search and Start menu issue pertinent enough to address right now, despite many users being affected.

Around 75 users have made similar posts regarding the issue on the Microsoft support forum:

KB4524147 originally caused a critical error when using Start Menu AND it prevented my printer from printing. The latter was because of some mess up with the print spooler. I uninstalled KB4524147 and BOTH problems disappeared. This morning, I updated with KB4517389. The printer seems to work, BUT I receive a critical error when using the Start Menu. I suppose I need to uninstall KB4517389?

Reddit users have also instigated threads related to the issue:

Cumulative Updates: October 8th, 2019: Still breaks the Start Menu. “Critical Error”.

While the company insist they are investigating reports and feedback, the root cause still remains a mystery. Luckily, the October 2019 Patch Tuesday updates haven’t yielded any further issues of-note.
