Summary: Script built to update multiple Virtual Center Windows customization scripts in one easy step. Powershell Code: http://docs.google.com/View?id=ddvthst9_15fsx7vdgb Details: I have several customization scripts that all are configured in almost the exact same way minus IP gateway settings (thus the need for many specs). I needed to add a couple more run once commands to to fix an issue we were having with McAfee ePO agents that were statically installed on templates. The agent apparently generates a unique GUID and mac address in the registry associated with the systems name. To fix this when cloning the template I needed to delete these two registry entries so ePO would regenerate new ones when the cloned template builds it would register properly with ePO. There is probably a bit more that can be done with this script, but it’s done what I need it to do for now.
