This script sample can enable the Windows Search service on Windows Server.
By default, Windows Search Service feature is disabled on Windows Server. You must manually enable the Windows Search service in Windows Server 2008 R2 and in Windows Server 2012. There will be too much manual work if multiple server machines need to be enabled. We can use script to help you enable the Windows Search Service for Windows Server automatically
