Do you use aSuite (v4.9) or LiberkeyMenu (v5.0 beta) ?
Even if the option exists, aSuite does not know very well about running processes and can't prevent from running some of them because of *LKL.exe => *.exe exe translations.
If you use the new menu, it won't occurs anymore if you use inside menu shortcuts (but won't works if you use shortcuts from desktop for instance)
If you still wants to use the old menu, try to use autostart developped by skybird (in french and no more developed/maintained as the new menu has implemented 90% of its functionalities)
