The startup of this service signals other services that the Security Accounts Manager (SAM) is ready to accept requests. Disabling this service will prevent other services in the system from being notified when the SAM is ready, which may in turn cause those services to fail to start correctly. This service should not be disabled.
This service also exists in Windows 10, 11, 8, Vista and XP.

The Security Accounts Manager service runs as LocalSystem in a shared process. It shares the executable file with other services. If the Security Accounts Manager fails to load or initialize, the error is recorded into the Event Log. Windows 7 startup should proceed, but a message box is displayed informing you that the SamSs service has failed to start.
Security Accounts Manager will not start, if the Remote Procedure Call (RPC) service is stopped or disabled.
If the Security Accounts Manager is stopped, the following services will not start and initialize:
