Default Behavior

Windows Time is a Win32 service. In Windows 11 it starts only if the user, an application or another service starts it. When the Windows Time service is started, it logs on as NT AUTHORITY\LocalService and running in a shared process of svchost.exe. If Windows Time fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the W32Time service startup failure.
