It is second Tuesday of the month, which, for Windows users, means one thing: mandatory Patch Tuesday updates, so brace yourself and your PC for the latest wave of security updates and fixes that Microsoft prepared for you. If you are still on Windows 10 in the Extended Security Updates program, you can download KB5075912, with build number 19045.6937.

Besides traditional security updates and some bug fixes, today's release begins the process of Secure Boot certificate updates, which Microsoft announced earlier today. They are mandatory to keep your PC safe and compatible with software that relies on Secure Boot. You can read more about that here.

Here is the changelog:
  • [Fonts] This update includes changes to Chinese fonts to meet GB18030-2022A compliance.
  • [OS Security (known issue)] Fixed: After installing the Windows security update released on or after January 13, 2026, some Secure Launch-capable PCs with Virtual Secure Mode (VSM)enabled are unable to shut down or enter hibernation. Instead, the device restarts.
  • [Folders] Fixed: This update fixes an issue that affects folder renaming with desktop.ini files in File Explorer. The LocalizedResourceName setting was ignored, so custom folder names did not show. Now, custom folder names appear as expected.
  • [Graphics] Fixed: A stability issue affecting certain graphics processing units (GPUs) configurations.
  • [Secure Boot] With this update, Windows quality updates include a broad set of targeting data that identifies devices and their ability to receive new Secure Boot certificates. Devices will receive the new certificates only after they show sufficient successful update signals, which helps ensures a safe and phased rollout.
 
This looks like a typical Windows 10 “B” (Patch Tuesday) cumulative update write-up, but I can’t verify the exact KB number/build/changelog from here, so treat the Neowin post as secondary until you confirm it against Microsoft’s own documentation.

How to verify the update is real and applies to your PC (recommended)
  • Check Microsoft’s KB support article for the update ID (KB5075912) and confirm the “OS Build” it lists matches what you expect for Windows 10 22H2 (19045.x).
  • Confirm via Windows itself: Settings -> Update & Security -> Windows Update -> View update history, and verify the KB is listed.
  • Confirm the installed build number with winver (it should show 19045.6937 only after the update is installed).
  • If installing manually, only use the Microsoft Update Catalog entry for that KB (not third-party mirrors).

Secure Boot certificate rollout: what matters from a security standpoint
Secure Boot trust/certificate maintenance is not “optional hardening” in the way many settings are—if Microsoft is rotating/adding Secure Boot-related certificates/targeting data as part of Windows quality updates, staying current helps avoid both security gaps and future compatibility/boot trust issues with components that rely on Secure Boot.

Practically, the safest approach is simply: keep receiving the monthly quality updates through the official channels, and avoid disabling Secure Boot to “work around” unrelated problems unless you fully understand the impact.

Before installing (low-risk precautions that prevent headaches)
  • Make sure you have a current backup (ideally a full system image).
  • If BitLocker/device encryption is enabled, ensure you have the recovery key saved somewhere you can access offline (Microsoft account/printout/secure vault).
  • Plan for at least one reboot (sometimes two) and a little extra time if servicing stack/boot components are involved.

If you see shutdown/hibernation restart behavior (VSM / Secure Launch systems)
The quote you pasted mentions a shutdown/hibernation restart issue affecting some Secure Launch-capable PCs with VSM enabled after January 13, 2026 security updates, and that this release includes a fix.

If the issue persists even after the cumulative update is installed, the safest “don’t break the machine” approach is:
  • Temporarily avoid hibernation until Microsoft’s fix is confirmed installed (use Restart / full Shutdown).
  • Don’t start toggling Secure Boot / VBS / VSM features blindly—those changes can have security and recovery implications.
  • Rely on Microsoft’s known-issue guidance for that specific KB/build once you’ve confirmed the exact update you’re on.

Bottom line: verify KB5075912/build 19045.6937 against Microsoft’s KB page and install via Windows Update (or the Microsoft Update Catalog) after taking basic precautions; that’s the most reliable way to stay secure and avoid bad “workarounds,” especially when Secure Boot-related changes are in play.
