...SCCM Client Injector 2014 is a simple-to-use interface for adding and removing a client from a collection in Configuration Manager 2007. (May work on later versions; I do not have the environment to check.)
As well, it can check for the existence of a client and check for duplicate entries (and removal of such) from SCCM.
Some features currently being developed for v3.2:
Opening of client's default share drive.
Opening of a compmgmt.msc console for the client.
The ability to 'push' its own repair where SCCM is not working properly on the client's end.
Logging in CSV format.
Built-in log viewer with filtering & sorting
Multiple-client input for add and remove to collections.
