Yes, you can move Windows.

You may duplicate the storage but cannot transfer Windows directly.
If you own a Samsung SSD (other brands may have similar options), these drives usually come with a disc containing cloning software. You can use it to duplicate everything. My advice is to begin with a clean Windows installation, so you can assign programs to either the SSD or the main hard drive. I only store my most frequently used applications on the SSD (including Windows). Steam can be saved to the SSD, but when downloading games you can switch it to your hard drive.
I think the Windows disk might have a recovery option. It hasn't worked much in a while.
