virtualization of drivers or hardware control utilities

Looking in TaskManager Processes after enabling the Virtualization column I
noticed that several drivers or driver configuration utilities had
virtualization enabled while others did not. There haven't been any
particular problems with the related devices but it had me wondering whether
this setting was correct or whether it would be better to turn
virtualization off for all hardware related processes? Or should it just be
left alone.

Driver related processes that show virtualization enabled are CCC.exe (ATI
Catalyst), MOM.exe (Catalyst monitoing program), KBD.exe (keyboard driver)
and Ipoint.exe (mouse settings utility). Driver related processes that don't
have virtualization enabled are COCIManager.exe (camera control interface),
RtHDVCpl.exe (HD audio control panel), BJMYPRT.exe (Canon My Printer),
Quickcam.exe (camera software), LVComSer.exe (Logitech video COM service)
and Communications_Helper.exe (Logitech communications Manager, for
webcams).
