If I get a new SSD, will my Windows recognize it as a new machine?

I don't have any copies of Windows left so if replacing the SSD means it's a new machine I gotta replace the OS as well

No, OEM copies of win 7 and older are tied to the motherboard and not the HDD/SSD. So as long as the motherboard remains unchanged you are fine.

Changing the drive is fine.
Changing the motherboard is the trigger for "new PC".

Well, if you get an SSD as your boot drive, you're going to have to reinstall Windows on it. But you won't need to buy a separate license for just changing the storage device.
