Nero 7 installs some crap called Nero Scout.  If you installed Nero, upon reboot you will find a search bar within your TaskBar.   Nero does not include an option to disable this or not to install this pest.  So here is the quick way to disable this once installed.
Click Start Run and paste this whole entry and Enter.  Optional you can open a cmd line and run each regsvr32 entry.  The /u is uninstal and the /s is silent (no confirm or fail notice).

Cmd.exe /c regsvr32 /u /s "%ProgramFiles%\Common Files\Ahead\Lib\NeroSearch.dll" && regsvr32 /u /s "%ProgramFiles%\Common Files\Ahead\Lib\NeroSearchBar.dll" && regsvr32 /u /s "%ProgramFiles%\Common Files\Ahead\Lib\NeroSearchTray.dll"

Once completed you will see the search bar disappear…  Done.
NMIndexingService service can be stopped but will continue to start when needed, set at Manual.   Kill the startup entries for Nero and it will stop loading at boot.  NeroCheck is ok, this only checks to see if the aspi entries has been altered, then ends.
