Hi guys, I am trying to reproduce Process Exporer's feature to tag a process running on the current machine with a Comment (Please see the Comment section in the Process properties in Process Explorer). I couldn't find any way to do it with managed code, had a try with wmic utility but I wasn't able to find a way to set a property to an existing process. Also, searching the web returns some pretty vague responses since all the search terms are so general.. If anybody has at least a hint I will appreciate it. Alex. P.S I am using C# for the project but I am opened to use unmanaged code if that's what it takes :)
