>Being required to use my pinky to try and hit CTRL

I use Windows, OSX, and Linux fairly often (mostly Windows, then OSX, Linux here and there). For me, the most frustrating thing about Windows, a minor point but it bugs me, is that you can't remap the CTRL key without having admin rights.

This is a user-controlled preference the OS has in the box, in OSX and Linux distros I've used. On Windows, you need to edit the registry (!!) or use the SysInternals driver, which requires Admin rights. I haven't found another way to do it that doesn't require installing more software and/or admin rights.
