I wanted a clean install of SharePoint 2010 so I recently uninstalled it as well as deleted all the content databases from Central Admin and SQL Management server. I then re-installed SharePoint 2010 and to my surprise and dismay, I noticed all the features and feature ID's and GUIDs were still there.
The whole reason I did this uninstallation process is because I have been developing on my SharePoint site for months and it is clogged up with artifacts and remnants of various solutions and features and I wanted a clean slate.
Does anyone know what needs to be done to completely remove all traces of anything SharePoint 2010 related? Does the GAC need to be cleaned out? Does each feature and solution need to be deactivated and removed? Any help is much appreciated.
