Find VMs Where the Running OS Does Not Match the Configured OS.

#A quick grep of all VMs in a vcenter, with the configured and running OS (detected by a valid version of VMware tools installed)
#This is a great report if you find out some Admins were running “upgrades” from windows 2008 to 2012 and never reconfigured the VM OS setting.
