How do I actually get opengl?

I made a mistake earlier by permanently deleted opengl because I didn’t know what it was. After asking and looking around I used DDU to make a clean clear like someone said and then they said to download opengl again. How do I do that? Windows 10, btw

See:

in the OpenGL Wiki.
