Offline Updating Hyper-V VMs

Have a lot of VMs which are offline and want to check if their Integration Tools are up 2 date? I wrote a little script which does just that. And as a bonus, when the VM has 2008R2 or higher installed, the Integration Tools are automatically updated with the latest version available on the Hyper-V host you run this on!
