[CentOS] Disable auto window maximize

Job #1 for me with CentOS 7 is to disable the automatic window maximization.

Some googling found this command:
$ gsettings set org.gnome.mutter auto-maximize false
No such schema 'org.gnome.mutter'

and this:

$ gsettings set orh.gnome.shell.overrides edge-tiling false
but that had no visible effect.

I couldn't find anything under Applications->documentation and I didn't see anything in the on-line GNOME help manual.

I looked under Applications->System Tools and Applications->Utilities. I found the Tweak Tool but didn't see anything in there either.

Can someone point me to some documentation on how to do this?

Thanks,
Steve
