Windows 11 KB5062633 Update: A Critical Notification for Enterprises
Microsoft has introduced the Windows 11 KB5062633 update for users on the 23H2 version. This optional update is currently being rolled out and includes an important alert for enterprise environments regarding the impending expiration of Secure Boot certificates. These certificates, which were initially issued with Windows 8 in 2011, are set to expire in June 2026, drawing closer with each passing month.
New certificates were released in September 2023, and according to Microsoft’s documentation, users won’t need to take manual action, as the process will be managed automatically. However, it is essential to stay vigilant with system updates to ensure the installation of these new certificates, as Secure Boot plays a crucial role in safeguarding your core system files from malware and preventing unauthorized firmware alterations.
Despite the significance of these updates, the documentation appears to be overly intricate for general consumers, leaving personal PS users without clear guidance. In contrast, enterprise users can explore options like adjusting registry settings or system policies for proper management.
