Default Behavior

Windows Search is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the Windows Search service is running as LocalSystem in its own process of SearchIndexer.exe. If Windows Search fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the WSearch service has failed to start due to the error.

Dependencies

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

While Windows Search is stopped, disabled or working incorrectly, the following services do not start:

The WSearch service is using the SearchIndexer.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.
