Hey F4llout, thank you for this guide.
Anyway, I have to explain something about widescreen in Hitman: Codename 47 (I cannot say anything about Hitman 2).
Yeah, you can play in 1920x1080 or wathever you want, but the game does not resize the image correctly, the process he does is like a bad film restoration company, that makes a 4:3 Film (1.22/33.1 aspect ratio) looks panoramic (16:9, 1.85.1, 2.22.1..,). You can play it on widescreen, of course, but your image will be cuted, no extended.
Heres is a comparison:
4:3

And this is how I'm playing right now on my PC:

Anyway, as you see, it's not very goodloking, and UI seems pretty small sometimes, maybe the best choice is to run the game on its default resolution, with no scaling (and vertical black lines, instead of desktop).
PS: By the way, no, I have not my task tab at the left, it is only when I playing hitman.
