It's a bad idea, but..if the policy got corresponding registry value, then...
Take the two Registry.pol file under :\Windows\System32\GroupPolicy\ ref
The Group Policy Object Editor stores registry-based configuration
settings in two Registry.pol files, stored in folders under the
:\Windows\System32\GroupPolicy\ folder. One file contains
computer settings and the other file contains user settings. The Group
Policy Object Editor saves the settings to these files on exit, and
imports the settings on startup.
Better idea to manage your computer;
Create a GPO that target that computer and make it apply to other computers you want.
By copying the .pol file you fall like it was on older system like NT4 with poledit to make policies.. It's a way back to a nightmare for many tech that lived that period IMO, but welcome to the boat if you use that method I guess.
