A SSD makes many things quicker.
Opening files and populating thumbnails takes lots of random I/0. That is 50x faster than even a velociraptor.
A windows install might take 15 minutes vs. an hour.
If you must do a clean install, use windows easy transfer to export your settings to the hard drive.
Install windows on the ssd without your hard drive connected. If you leave it connected things get messed up. Windows will try to put a hidden recovery partition on the hard drive.
After windows is installed, you can reconnect the hard drive, and you will have access to all your files.
You can import your settings, and there will be a report on which programs need to be reinstalled.
Your programs will not be available because you have a new registry and your aps are not known to it. You will need to reinstall them.
I have Used the Samsung migration utility to clone a hard drive to a ssd. It works well(must be to a Samsung ssd)
If your source drive is too large, they have an option to do a selective clone.
(which I have not needed to use)
I think you can tell it to not move your large files. That would let you clone windows and some apps which is a much easier conversion.
When you are all done, you can simply delete the windows files on your old hard drive.
There will be some boot stuff and a small hidden partition, but it is probably more trouble than it is worth to try to recover that space without reformatting and dealing with your data files.
There may be some other clone utilities with the same capability, but I don't know them.
