SCCM right click tools adds multiple ‘Client Tools’ entries

During a recent SCCM deployment I was installing the usual handful of 3rd party tools to add options to the SCCM console (more info here http://www.myitforum.com/myitwiki/SCCMTools.ashx).

This was the first time I had seen an issue with them – they seemed to add multiple entries of ‘Client Tools’ to the right-click context menu as shown below:
 

 
Even after an uninstall of the tools they were still there. It seems there is a directory where all these console extensions are located. The solution was simply to delete the entries from this location. As shown below, these 3rd party tools add directories to the <SCCM console install location>/AdminUI/XmlStorage/Extensions/Actions. I just deleted all these folders and reinstalled the tools.
