A Guide to Fixing "MS Service Manager Certificate Expired" Errors on Windows 11
Have you encountered the dreaded "MS Service Manager Certificate Expired" error on your Windows 11 system? This error can be frustrating, preventing you from accessing crucial system services and functionalities.
This error message often appears during system updates, or when you try to open certain applications. It signals that the digital certificate used by the "MS Service Manager" service has expired, leading to security concerns and system malfunctions.
Understanding the Issue
The "MS Service Manager" (MSM) is a vital component of Windows 11. It handles various tasks related to system services and applications.
