Check out the screenshot below, I want to extend my C partition (where Windows is installed) into the unallocated free space shown. This space was cleared up by shrinking the D partition. I can extend the D partition if I want to, but not the C.
Why not?

It's because you can only extend a partition if the blank space is directly following it. Your D: partition is in the way.
Perhaps look into a partitioning program like GPartEd.
