Microsoft acknowledges critical fault with KB4524244 update for Windows 10

3 min read

Microsoft released a KB4524244 security update to all versions in addition to the cumulative update when it released routine updates this month to address UEFI security vulnerabilities on some models. This independent security update is being pushed to all editions between Windows 10 v1607 and Windows 10 v1909.

After Microsoft pushed this security update, a large number of users found that the security update was faulty, which caused some brands of computers to fail to start directly after installation.

“Installing this update trashed my user profile and created a temp. Uninstalling it returned my user profile back to near normal. I tried installing it a 2nd time with the same results.  Also, it reinstalled One Drive (which I don’t use) and started migrating files to the cloud after it demanded I log in with my Microsoft account. So, I uninstalled it again and restored my original user profile. After the 2nd install and removal, Outlook was trashed as well and had to be fixed. Does Microsoft even test these updates before they push them out.”

“Same problem here on several machines, and they are all running on AMD Ryzen cpus. Installing (trying to install) KB4524244 results in the machine freezing and after recycling the power there’s an uefi error (see the image). This has happened on several machine (both HP laptops and desktops), all running on AMD Ryzen cpus, and all with default bios/uefi settings with the newest bios installed. Windows 10 1809, 1903 or 1909 on all.”

The main reason for this problem is that Microsoft did not contact the manufacturer for confirmation or testing and then pushed directly when it released the firmware security update.

It appears that this security update is a universal update that applies to all models of all manufacturers, so Microsoft did not contact companies such as HP separately for testing.

It is only after the user installs that it is discovered that the update may cause the system to fail to start normally. Installation updates for devices of multiple brands such as HP will fail.

At the same time, Microsoft also confirmed that if users reset, there will also be a reset error problem, and to solve this problem, you can only uninstall this independent security update.
