Answer 1

bcdedit /set {bootmgr} locale en-US

Answer 2

In my case the C:\ system partition was set to en-GB; I tried the command line above and it didn't reset the C:\ partition. I had to modify it to this: bcdedit /set {current} locale en-US, and then my locale changed on my C:\ partition. I kept getting the British spelling of Centre every time it appeared in my menus or commands/options, e.g. Network and Settings Centre.
