Image Stretch with window resize

How and I prevent my Images from resizing themselves? What I mean is that when I load a sprite, in this case a rectangle with a logo on it, how can I prevent it from being stretch with the window.
It should look like:
What it does look like:

Does anyone have any suggestions? I've already tried setting a sf::View, which did not work.

window.getSize().x

was a thing.
