Microsoft patched six zero-days, but you may want to wait to update

February's Patch Tuesday refreshes expiring Secure Boot certificates and addresses a range of feature and security bugs. The certificate updates began with January's rollout and continue now because many certificates are due to expire in June. Secure Boot uses certificates to ensure only trusted programs run during the boot process.

The new certificates apply to both Windows 11 and Windows 10; Windows 10 machines need to be enrolled in the Extended Security Updates (ESU) program to keep receiving important security updates and patches through October 2026. The update fixes feature issues: on Windows 11 it resolves a full-screen gaming glitch and a problem preventing some PCs from connecting to certain WPA3‑Personal Wi‑Fi networks.

Windows 10 fixes address Chinese fonts, certain GPUs, custom folder names in File Explorer, and a January-introduced bug that caused some Secure Launch–compatible PCs to restart instead of shutting down or hibernating.
