That was written in Delphi. I don't see what's the harm of that key. I'd ignore this one.
From time to time I run the program Ccleaner, and when I use the registry cleaner part, it finds this "key". I delete it, but when ever I run the Ccleaner program again, and I only run it every once in a while, the same 'key' is always there. I did a quick Google search, but didn't see anything.
Thanks in advance
