Default Behavior

Windows Search is a Win32 service. In Windows 7 it is starting automatically after the operating system is started. Then the Windows Search service is running as LocalSystem in its own process of SearchIndexer.exe. If Windows Search fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the WSearch service is not running because of the error.

Dependencies

Windows Search is unable to start, if the Remote Procedure Call (RPC) service is stopped or disabled.

Restore Default Startup Configuration for Windows Search

Before you begin doing this, make sure that all the services on which Windows Search 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 commands below, paste them into the command window and press ENTER:

sc config WSearch start= delayed-auto
sc start WSearch

3. Close the command window and restart the computer.

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 7 installation media.
