Toshiba Satellite windows 8 - small apps?

Whenever I open minecraft, it is really, really small at the start. If I make it bigger, it is small again when I next open it.
It doesn't really bother me much with minecraft, as I maximise it anyway.

However, I'm setting up the sims but it is really small and it doesn't maximise. Everything is squished together and you don't know what you re doing.

Help?

Added (1). I didn't really make it clear, but I mean the minimised window thingy is really small.

The sims needs to run on the entire screen, you need to check your settings. But you have one of the worst laptops for gaming there's
