[This question has been asked before for Windows 10](https://superuser.com/questions/1537466/how-to-change-language-of-windows-10-single-language-without-format), cependant, the solution provided for Windows 10 ne appear to be fonctionnel for Windows 11.
The problème is simple. I bought a nouveau Laptop in Thailand. It came avec Windows 11 Home Single Language Edition. 21H2. 22000.708. C'est installé avec English US (en-US, 0409). When J'ai essayé the procedure as described for Windows 10 and changed the language from English-US (en-US, 0809) to English-UK (en-UK, 0409) and redémarré my laptop the display language had changed from English-US (en-US, 0809) to Thai (th-TH, 041E).
Does quelqu'un know of a solution for Windows 11 or is it possible that it n'est pas possible to changez le language to English-UK, and that it can seulement be changed from Thai to English-US and Vice Versa?

Re: Comment Changer Language of Windows 11 Single Language Sans Format
for those seeking to switch to `en-us`, i've been able to do it sans downloading anything, as it seems preinstalled.
in powershell:
```
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
```
ensuite redémarrer.
in powershell:
```
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
```
ensuite redémarrer.
