If you’re still running Windows 10, February’s update is one of those updates you probably shouldn’t ignore.
Yesterday, Microsoft released KB5075912, its latest update, as part of its February 2026 Patch Tuesday cycle. While there are no shiny new features, there’s a lot happening under the hood.
The company says this security update includes fixes tied to earlier releases in January and addresses a long list of vulnerabilities, including six zero-days, a cybersecurity vulnerability that increases the chances of hacking.
After installation, Windows 10 moves to Build 19045.6937, and Enterprise LTSC 2021 updates to Build 19044.6937.
The most urgent fixes are security-related. With this Patch Tuesday, Microsoft says it has addressed 58 vulnerabilities.
Microsoft explains that Windows quality updates now include “a broad set of targeting data that identifies devices and their ability to receive new Secure Boot certificates.” Systems receive them only after showing “sufficient successful update signals,” part of what Microsoft describes as a safe, staged rollout.
The company also released some practical bug fixes. One issue caused some Secure Launch-capable PCs with Virtual Secure Mode enabled to restart instead of shutting down or entering hibernation. Microsoft notes that the error has been fixed.

File Explorer users get relief too. “[Folders] Fixed: This update fixes an issue that affects folder renaming with desktop.ini files… custom folder names appear as expected.” There are also updates to Chinese fonts for GB18030-2022A compliance and a fix for “a stability issue affecting certain graphics processing units (GPUs) configurations.”
For users in the Extended Security Updates (ESU) programme or on Enterprise LTSC, installation works as usual through Windows Update. Microsoft also reminds administrators that the latest Servicing Stack Update must be installed first, otherwise the patch may not appear.
There are “no known issues with this update,” according to Microsoft.
Since mid-2025, Microsoft has warned that several Secure Boot certificates from 2011 will expire in June 2026. The company reemphasised this in the new updates.
Stepping back, this patch highlights where Windows 10 now sits. There are no feature expansions. The focus is maintenance, risk reduction, and certificate transitions ahead of 2026 deadlines.
