How can I set h,j,k,l to be movement keys in VIM for Windows?

How can I set h,j,k,l to be movement keys in VIM for Windows?

I installed VIM for Windows due to issues with my Samba setup (I'm unable to edit a file on my linux machine and use it on my windows machine without copying it explicitly). Imagine my surprise when I found that h,j,k,l aren't movement keys in VIM. I'm forced to use the arrow keys!
