I'm using Windows 10 Professional. When I initially installed it, I chose German, and I want to change the display language to English instead. That includes right-click menus, Explorer, etc.
I've tried the following settings:
Under Region and Language, I have removed everything but English (US) and made sure it's set as the default:
Under Control Panel > Language, it also only says English (US):
.
In that same menu, under options, it says that no language pack is available:
.
I have also tried all of the above with English (UK) instead of English (US), didn't work either. I've rebooted between changes to no avail.

All right, found a solution.
I downloaded the language pack from https://support.microsoft.com/en-us/help/14236/language-packs and installed it with
lpksetup.exe
which comes with windows. Now my system is fully translated.
