Microsoft released cumulative update KB5075912 for Windows 10 version 22H2 as part of the February 2026 Patch Tuesday. This update is intended for devices participating in the Extended Security Updates (ESU) program. The cumulative package KB5026435 (build 19045.6937) is available for Windows 10 version 22H2 on x86, x64 (amd64), and ARM64 processors. As a reminder, support for Windows 10 ended on October 14, 2025, and the system now receives updates only through the ESU program.
- Fonts. This update includes changes to Chinese fonts to ensure compliance with the GB18030-2022A standard.
- Security. Addressed an issue where after installing Windows security updates released on January 13, 2026 or later, some PCs with Secure Launch support and Virtual Secure Mode (VSM) enabled would restart instead of shutting down or entering sleep mode correctly.
- File folders. Fixed an error in File Explorer where renaming folders containing desktop.ini files ignored the LocalizedResourceName parameter, causing custom folder names not to display. User-defined folder names now display correctly.
- Graphics. Addressed a stability issue affecting certain graphics processor (GPU) configurations.
- Secure Boot. Microsoft is updating certificates used to verify trusted components during Windows boot. To avoid startup issues on some PCs after the update, deployment is being done gradually and is currently limited to devices with a confirmed stable update installation history.
