I have just checked my 7.5 HF4 system and have found that all six "Site Management > Settings > Monitor Service > Advanced > Windows Remote Monitoring Server <architecture> <action>" policies are enabled!
This obviously does not make sense, as the Uninstall policies should only be used either when the Install & Upgrade policies are disabled, or have had their targets changed so that they do not cover the servers that you want to target the uninstall process against.
How did this get passed QA one asks?
