VMware PowerShell contest

Well for those of you who know/or care I participated in the VWAre PowerShell Contest. I didn't win :( some say I should have, some just don't say. The script I submitted basically shows you what services are on your vm's. At the moment it uses windows WMI to find the services on each box, to do this it uses powershell's WMI. And it can filter out most of the "standard" services thus showing you if it has a SQL instance, or a web service. This helps when you are trying to cut out extra services/processes from running on your boxes to increase performance and/or get more vm's on the same boxes. Yeah I know ESX server uses ram to consolidate things across vm's so there's less physical ram usage, great but it doesn't do that for processing. So do you really need the windows audio service in a VM? I've had it in a few. The other purpose is to findout what the heck your running. Fine if it's a webserver, but did you know it has a Postgres SQL and some other weird service that some guy wrote that you never knew existed? - And may just have a huge memory leak? In any case here's a link to it here. It's on googles document site which doesn't support .ps1 files so you have to rename it from a .txt to a .ps1. When I have time I'll start updating the script in between everything else.
