True - needs WMI core 1.5 add-on -- see Run-Time Requirements here:

I wanted to point out, though, that passing a Ruby string
to WIN32OLE.connect means those '\' must be doubled:

":\\\\.\\root\\cimv2"
#  000  3a 5c 5c 2e 5c 72 6f 6f 74 5c 63 69 6d 76 32     :\\.\root\cimv2

.... rather than ...

":\\.\root\cimv2"
#  000  3a 5c 2e 0d 6f 6f 74 09 6d 76 32                 :\..oot.mv2


Alternatively, '/' appears to be accepted by WMI:
"winmgmts://./root/cimv2"
