AttributeError: <unknown>.Win32_PerfFormattedData_PerfOS_Processor
Anyone could explain this traceback? Made a remote call on WIN7 machine.
AttributeError means that the object c doesn't have an attribute Win32_PerfFormattedData_PerfOS_Processor.
The "" indicates that Python asked c to describe itself and c returned the string "" (which obviously isn't terribly helpful). It appears you've created c, so it would illuminate the problem more if you would include the code that created c.
My best guess is that c is some sort of WMI wrapper, but that WMI object doesn't have the Win32_PerfFormattedData_PerfOS_Processor function/method/attribute.
The underlying cause is that either you're not using c as designed (maybe you're missing some run-time components) or c isn't initialized properly.
UPDATE:
this worked: i.e. at cmd --> lodctr /q
