Hi guys, sorry to revive this topic! 
What if I want to change the KEY name...
I've added a key to all my vmx files with a typo (dammint!) and now I have to correct that.
I was using this approach: http://blogs.vmware.com/vipowershell/2008/09/changing-vmx-fi.html but I've set the $key = "RemoteDisplay.maxConnection" instead of $key = "RemoteDisplay.maxConnections"
Does anyone know a easy way to fix that?
Thanks in advance.
