There is not a more "straightforward way" for a program to do this without modifying the registry. The ideal solution is to track the keypresses in a table (std::map, Dictionary, etc). The intent of this on MS's part is to prevent viruses/malware from taking control of the keyboard and preventing the user from using important keyboard combos such as WinKey-L and Ctrl-Alt-Delete.

You can, however, remap the keyboard scan codes in the registry if keyboard hooking is not for you. This isn't ideal, since it's hard to reverse (especially if you make a mistake, or your program crashes, or the user uninstalls the application but the registry hack is not reverted). But it does work. Here are some references:
