Windows 10 KB5075912 February 2026 Patch Tuesday Update Out Now

Last month, Microsoft released KB5073724 as Windows 10’s first Extended Security Update for 2026. It’s February, and now we have another Patch Tuesday update for Windows 10 users under the Extended Security Updates program. The latest patch comes as KB5075912, with build number 19045.6937. The update lands alongside February 2026 Patch Tuesday updates, KB5077181 & KB5075941, for Windows 11 version 24H2 & 25H2 and 23H2, respectively.

Besides the security improvements and bug fixes, this update kicks off the rollout of Secure Boot certificate updates. These updates are required to keep your PC safe and compatible with software that relies on Secure Boot.

Here’s what’s fixed and updated according to the update’s 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 ensure a safe and phased rollout.

As always, this update is also available via Windows Update and the Microsoft Update Catalog for offline installation.
