Default Behavior

Windows Perception Service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Windows Perception Service is started, it is running as NT AUTHORITY\LocalService in its own process of spectrum.exe. If Windows Perception Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the spectrum service has failed to start due to the error.

Dependencies

Windows Perception Service cannot be started under any conditions, if the Remote Procedure Call (RPC) service is disabled.

Restore Default Startup Configuration for Windows Perception Service

Before you begin doing this, make sure that all the services on which Windows Perception Service depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config spectrum start= demand

3. Close the command window and restart the computer.

The spectrum service is using the spectrum.exe file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
