I'm developing a few Runescape-related programs and am curious as to what my limitations are in terms of a target audience. I'm curious as to which operating system you use to play Runescape, or to use any Runescape-related programs.
Voted, it seems the majority of people use Windows 7 these days. Some may still use XP and such though. I think you should aim at Windows 7 mate.
What kind of program are you making?
Btw I don't think anyone uses Windows 8![]()
