Windows 7: Is there a way to reroute CMD+Left to Pos1 and CMD+Right to End?

Using Mac OSX, I quickly grew accustomed to CMD+Left and CMD+Right to jump to the beginning or the end of the line in a text-editor. On my work-PC, these combinations only jump one word left or right, as ALT+left or right to on the Mac.

Is there a way achieve these keybindings in Windows 7 too? The system preference for keyboard only lets me pick cursor speed and such nonsense.
