Software that let's you migrate ONLY your OS (windows 7) from HDD to SSD ?

I'm finding alot of videos on youtube about migrations but programs like Easeus, AOMEI and similar not only move your OS but all your files. That's what I do NOT need. I need soft that let's me move ONLY my windows 7 from my HDD to a newly installed SSD. Soft can be paid or free. Any ideas?
