How do I transfer just the OS to new SSD?

Use dd on a Linux disc. I've done it before and it works flawlessly

dd is nice, It would not work for the OPs request.
dd copies the drive bit by bit.
It can be set for less than the whole drive, due to disk fragmentation it is pretty unlikely that windows occupies a single continuous section of the drive.
dd certainly could be useful for copying the boot-loader which may or may not be copyable via the method described in my previous post.

I found cloning to be the simplest way. Acronis True Image. Took about half an hour for me . Worked great.

I just bumped into this program. It lets you move applications to new locations and "re-maps" in Windows. You should be able to use it to move what you don't want on the SSD.
