Desktop Search Enable / Disable

In RegEdit, go to HKEY_CURRENT_USER\Software\Microsoft\Windows Desktop Search\DS and set "ShowStartSearchBand" to 0, and you’ll get the default search behavior back.

And while you’re at it and poking around in the registry, you might as well go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex and set FilterFilesWithUnknownExtensions to DWORD with the value of "1" in order to enable full-text searching of files (like code!) that Explorer by default skips over.

I am also trying
MSConfig 
and Start Control Panel Administrative Tools Services
