well there are a few things added to the context menu but the only one iv added today is Kaspersky AV which is there new RC for Windows 7 which added scan file/folder, as it would.
Iv had a look with the app you pointed to but im really not sure about what im looking for, Iv also had a look with Glary utility's and found this.
but i cant find a corresponding entry with the context menu manager. So im a bit confused. I would send a copy of the context menu managers data but i can only save it as html and i cant attach that.
