The windows inside the phaser ring on the bottom are set inside recesses and look to be angled differently than the ones outside the phaser ring.
My question is, are the windows in the center (the larger ones in front of NCC-1701-D) supposed to be 10 Forward? If they are, 10 Forward was closed at the time.
No, 10-Forward is at the very forward-bottom rim of the saucer. The very front of the ship.
Those "windows" in the recess by the NCC number are said to be a deflector system to be used by the saucer when it's separated.
See on Rick Sternbach's blueprint here:
In the canceled DeAgostini Japan Ent-D project data, I came up with a way to have our cake and eat it too. I described a yard change which removed the chunky deflector hardware from the window area, and installed new transparent deflector arrays and restored the visual clarity to the rooms in that area. So folks serving aboard Galaxy class vessels can enjoy raktajino or prune juice or a really, really good margarita while taking in the view.
