Hello,

I would like to run msc command, but it seem impossible with MRI Ruby ( 2.3.3).

d:\>diskmgmt.msc                                         # ok
d:\>ruby -e "spawn('diskmgmt.msc')"            # error   : e:1:in `spawn': No such file or directory - diskmgmt.msc                                                                         
                                                                                                                                                                 
d:\>ruby -e "pid=Process.spawn('ruby -v'); Process.wait(pid) "                     # ok

It is not only mmc.exe which not work, it seem to be all commands in /windows/system32
