As far as I know it's just the standard "Windows Live Search"
I have just been trying to post a snap-shop of the search results, but am now having great difficulty getting through to PhotoBucket to be able to post it and ImageShack no longer recognises me.
The search result, which is the first item on the first page, when hovering the mouse over it, the metadata is actually word-for-word of what I wrote in the other thread with regards to this RAR extractor. "7z442"
I have just tried again after re-Ghosting my PC and the same thing still happens.
Weird or what.
Let you know the result later.
***********************************
The first shot is the result of the actual search.
When clicking the first link, then the scond shot is the result.
edit: if you look at the top-right of the second picture, you will also notice it has put kitz address in the address box.
