Editing Program?

[MrWells]

Hi , newbie question....
Just bought my first DSLR - Cannon EOS 650, I am a novice at photography. It comes with software -

Digital Photo Proffessional
EOS Utility
Picture Style Editor
Image Browser Ex

I am looking for the best photo editing software and was wondering what is generally used by most people? I've had a quick look on Youtube and the Photoshop tutorials look interesting. I used to have Adobe PhotoDeluxe 3.1 many years ago and got on well with the palette & icon setup.

I wont be getting into editing too deep so early on because I want to just go out there and take photos and get used to the camera and developing my own skills first. But I want to know whats available to me when I do .

Thanks, and nice forum ! think I'll learn alot here.
