How to fix Blue Screen of Death after installing Windows 10 October Patch Tuesday update

It appears that Microsoft is having some serious update quality control issues these days.

Shortly after the release of the Windows 10 October 2018 Update, users started reporting missing files after the upgrade, which forced the company to stop the distribution of the update. And now some users are reporting (via BleepingComputer) Blue Screen of Death (BSOD) errors after installing update KB4464330, which is the cumulative update that addresses the data loss problem.

According to several forums posts at the official Microsoft forums and on Reddit, some HP devices are crashing with the WDF_Violation error when trying to install the latest cumulative update. This problem isn't just happening on devices running the October 2018 Update but also on computers running the April 2018 Update (version 1803).

User Mikael Sillman, at the Microsoft forums, also reveals that the support team said that the company is investigating the problem, and it has temporarily paused the update on affected devices. However, if you're having this problem, there's a workaround that seems to be working for some users.

In this Windows 10 guide, we walk you through the steps to resolve the BSOD crashes after installing the October Patch Tuesday.
