How do I completely delete ASM?

Before you say this has been discussed in depth somewhere else here, I want you to know that I REALLY tried to find this topic, but couldn't. 

I would like to COMPLETELY DELETE ASM and all the test servers I have created so that I can start again. I am trying to set up a cluster, but I think the old settings, profiles, IPs and such are getting in the way. For instance, I had tried to create a second map (Scorched Earth) but I couldn't get it clustered, so I deleted the map profile, and the folders that I thought everything was saved in. I did this several times. The server manager is still starting Scorched from somewhere, and I don't know where. I thought I had deleted it, but I see it on the Steam, Add Servers menu. For some reason, it had a password, and I can't find the password.

I got a VPN, so now I would like to configure my VPN, and set up all the ports ahead of time, and then start fresh with ASM, but I want to know that it's not writing stuff into the registry, etc. 

Is it possible to do this?

Thank you in advance for any help anyone might offer.
