Restore Autorun Usb Sockets To On And Keep Internal Hdd To Off ?

Hi,
win 7 64bit pro
Kaspersky / Msoft looking 'assess damage to system after malware' wizard had me turn off autorun to internal and network HDDs and also another option I left ticked was removeable drives, on the finds and offered fixes after scan interface .
I need that last option undone, I need autorun for removeables on again, the wizard had an undo option but when run it hasn't undone it.

what must be done to turn back on autorun only for removeables. KiS sent me steps but they turn autorun on for everything.
