Hello everyone,

Three standalone security updates released as part of the February Patch Tuesday cycle were found to be problematic.

Known issues in KB4524244:

The security update KB4524244 released for all versions of Windows 10 addresses an issue in which a third-party Unified Extensible Firmware Interface (UEFI) boot manager might expose UEFI-enabled computers to a security vulnerability.

Microsoft has confirmed at least two known issues in the KB4524244:

• Using the “Reset this PC” feature, also called “Push Button Reset” or PBR, might fail. You might restart into recovery with “Choose an option” at the top of the screen with various options or you might restart to desktop and receive the error “There was a problem resetting your PC”.
  

• You might encounter issues trying to install or after installing KB4524244.
  

Known Issue in  KB4502496:

A second, related update, KB4502496, which addresses the same issue for Windows 10 version 1507 Windows 8.1, RT 8.1, Server 2012 R2, and Server 2012 has also been found to be problematic.

Issue found in the update above:

• You might encounter issues trying to install or after installing KB4502496.
  

To help a sub-set of affected devices, Microsoft has removed this standalone security update from its Windows Update servers and enterprise update channels. The company is working on an improved version of this update in coordination with our partners and will release it in a future update. 

Workaround for KB4524244 and KB4502496:

Since Microsoft has revoked and stopped re-distributing the above-mentioned updates, they will no longer be detected as missing and automatically pushed to your systems by Patch Manager Plus. 

If  KB4524244 and KB4502496 are already deployed and you are experiencing issues, you can search for these updates in the"Installed patches" view in Patch Manager Plus and uninstall it from all affected systems.

Note: Removal of this standalone security update does not affect successful installation or any changes within any other February 11, 2020 security updates, including Latest Cumulative Update (LCU), Monthly Rollup or Security Only update.

Known issue in KB4532693:

Another bug in the KB4532693 update is reported to hide user-profiles and their respective data on some Windows 10 systems. After installation, users can no longer view or access their original Windows 10 profile. Instead, they're logged into a blank/default Windows 10 profile where all their previous data is missing. However, no data is lost but hidden. This is caused by a faulty KB4532693 installation procedure. More precisely, the bug occurs because the Windows Update service creates a temporary profile to handle the installation procedure, but fails to remove it after installing KB4532693.

Workaround for KB4532693 bug:

If you're facing issues with the above update, you can uninstall the faulty KB4532693 and restore your old profiles. To resolve this issue, you can search for KB4532693 in "Installed patches" view in Patch Manager Plus and uninstall it from all affected systems.
