OneClick Optimizer query

This is embarrassing, as a Bitdefender Total Security user for more than a decade.

OneClick Optimizer comes with the options "Disk Cleanup" and "Privacy Cleanup" checked by default. But the "Registry Cleanup" is not.

What happens if I select "Registry Cleanup"? Will it delete important things that I may want to keep?

Basically, what is Registry Cleanup?
