Remove Lync 2010 Standard

I am trying to remove my single server Lync standard install via the Topology Builder.

By going in to my site -> Standard Edition Front End Servers -> Delete, i get the error A published pool hosting Central Management Service can not be removed

I cant remove the server from the topology so cant run the deployment wizard which will remove the role from the server.

As an edit from a post, I have now done the following:

1. Lync Control Panel -> Deleted all the Lync users from Lync ->
   commit all
2. Get-CsConferenceDirectory | Remove-CsConferenceDirectory
3. Get-CsExUmContact -Filter {RegistrarPool -eq "hqslc1.domain.local"}
   | Remove-CsExUmContact
4. Get-CsRgsWorkflow -Identity:Service:ApplicationServer:hqslc1.domain.local | Remove-CsRgsWorkflow
5. Get-CsDialInConferencingAccessNumber | where {$_.Pool -eq "hqslc1.domain.local"} |
   Remove-CsDialInConferencingAccessNumber
6. Get-CsCommonAreaPhone -Filter {RegistrarPool -eq "hqslc1.domain.local"} | Remove-CsCommonAreaPhone
7. Get-CsCallParkOrbit followed by Remove-CsCallParkOrbit -Identity "Home Park Orbit"
8. Lync Control panel -> Voice Features -> Unassigned Number, delete, commit all
9. Lync Control Panel -> Voice Routing > Route -> Edit -> Select all -> Delete -> Commit all

Despite the above, I still cannot remove the server or when running the Remove Deployment wizard no changes are made.
