A recent update has been released, addressing security vulnerabilities and improving system functionality. Key improvements include a fix for the Backup feature, resolving an "invalid credentials" error that caused automatic backups to fail when using Server Message Block (SMB). The update also enhances the Secure Boot feature by introducing high-confidence device targeting data, allowing more devices to receive new Secure Boot certificates. This update addresses outdated Secure Boot certificates for Windows 11 and Windows 10 users. The update, identified as KB5120249, is under 1 GB and is available only to PCs enrolled in the Extended Security Updates (ESU) program, which ensures Windows 10 PCs receive security updates until at least October 2027. Non-enrolled PCs lost security update support in October 2025.
