Windows on SSD, keep games on HDD?

I have currently installed a 2TB HDD in my notebook. Now I want to retrofit an SSD (480GB) and reinstall Windows on it. I have my current games on the HDD. Both hard drives will be present in my notebook and my question would be if I reinstall Windows on the SSD, can I play the games on the HDD or do I have to reinstall them on the HDD?

Reinstall everything Format HDD.

You will also have to reinstall the games. On Steam e.g. If you only have to say the same where the things are, the program carries out a short test and is good. So you save yourself a lot of download. You will have to reinstall everything that comes from other Medin.
