Thanks for the quick reply, will surely to try it later... Yeah, I already know about the GS_DLL and GS_LIB, my mistake is that I'm using HKCU intead of HKLM
I got it from ThumbApps.org, the latest version is 4.0.20, but you can update it to 4.0.21 by replacing the app files manually. I suggest not to continue talking about it, as it misleading the topic of this thread
