Well, it is at least in part how many linux distros configure Grub, it can be set up to boot the last selected OS, which I think should be the default... I changed it on all of my dual boot systems, though I haven't been using Windows all that much lately, so it hasn't been all that big of a deal for me.

I just wish that Windows hadn't changed the default update config to restart no matter which option is selected, since it makes that situation soooo much more annoying.
