The render is missing all the glow even though in the render preview it looks right, the render looks this way after saving it.

This is with no compositing done. enter image description here

I guess you open your picture file with Window's default picture viewer or something like that.

These default Microsoft softwares are very unreliable, I highly suggest you to use another one. There are plenty of free options that have a decent support for CGI standards, like XnView MP.

But basically, the issue is how your viewer treats alpha. Most simplistic software will make a choice among all the possible ways and give no tools for the user to choose. Leaving you with dirty viewings when the setting is wrong. But nothing is wrong with the picture, only the way the viewer displays it is wrong. And a more serious tool should at least give you options to correct it.
