How to fix KB4517389 BSOD errors

Microsoft rolled out KB4517389 at the beginning of October as part of the Patch Tuesday release.

Right after the release, many users started complaining about various issues. You can read more about the initial bug reports below:

• KB4517389 comes with installation problems for many
• KB4517389 causes Critical Error, Search bugs, and more
• Latest KB4517389 breaks Microsoft Edge on some PCs

Unfortunately, the saga of technical glitches doesn’t end here. Recent reports suggest that KB4517389 is now causing BSOD errrors.

On my laptop machine (but not on my desktop) I started getting BSOD failures in cldflt.sys after installing KB4517389. […]Uninstalling KB4517389 fixes the problem. Presumably, disabling cldflt.sys would do so, too, but I haven’t tried that yet.

So, if you’re also experiencing BSOD issues on your Windows 10 computer, rest assured you’re not the only one. There is nothing wrong with your machine. It’s Microsoft’s fault again.
