<p>for those seeking to switch to <code>in-us</code>, i’ve been able to do it without downloading anything, as it seems preinstalled.<br>
in powershell:</p>
<pre><code class="lang-auto">reg add HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language /v InstallLanguage /t REG_SZ /d 0409 /f
reg add HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language /v Default /t REG_SZ /d 1033 /f
</code></pre>
<p>ensuite redémarrer.</p>
