Can I reinstall Windows 10 in another language ??

[Windows Central Question]

My laptop came with Windows 10 Single Language Edition installed. I'd like to change the language from Portuguese to English. I'm thinking of using the Media Creation Tools to create a new media installation in English. My question is: Is the Windows 10 be activated with the "same key" in another language ??

Yes, key stays the same, only language changes. DON'T use Media Creation Tools if you want to change language of your pc Windows 10 installation. Open Settings > Time&Language > Region & Language > click + add a language and select English.
Wait for a while till language pack downloads and installs, click on English language and set it as default. Here you go, no need to reinstall Windows to change language.
