Windows 10 updates issues APR 2020

There’s yet another disastrous Windows 10 update, and this one could seriously mess up your PC. A new update released this month is leading to major crashes and deleted files, but there is a way to uninstall the update if you’re affected.

Windows Latest reports that numerous users have been struggling with issues caused by Windows 10 update KB4549951. This update, released on April 14, was first reported to be causing just computer crashes but newer complaints have pointed to the troublesome update as the cause of lost files.

Crashes and blue screen of death
This update is causing multiple types of crashes, with at least seven different stop codes reported (listed by Windows Latest):

PAGE_FAULT_IN_NONPAGED_AREA
CRITICAL_PROCESS_DIED
ACPI_BIOS_ERROR
INACCESSIBLE BOOT DEVICE
MEMORY_MANAGEMENT
DPC_WATCHDOG_VIOLATION
Portcls.sys

A few users are claiming that these shutdowns are occurring one after the other, meaning there’s no way to actually access the PC and fix the problem.

Disappearing files
In addition to the BSOD problem, other users are reporting that files, including pictures, documents and apps, are being deleted. This is similar to a Windows update from a few months ago, which was thought to be deleting users’ files but in fact was moving them to a new user profile.

How to uninstall Windows 10 update KB4549951
If you’re suffering from these problems, here’s how to uninstall the offending update.

Within the Start menu, go to Settings.
Select ‘Update & security.’
Select ‘Windows Update.’
Select ‘View update history’ -> ‘Uninstall updates’.
On this screen, find the KB4549951 update on the list, select it, and choose ‘Uninstall.’

Don’t push the panic button for updating with patches .. it’s better to wait and watch rather than inviting an issue.
