this is the real fix (even if the language is already mixed)...

open a PowerShell window in Admin mode, and then use the following command (this may take various minutes)...

$L='es-CL'; Install-Language $L -ErrorAction SilentlyContinue

and after that use the following command...

$L='es-CL'; Set-WinUILanguageOverride $L; Set-WinSystemLocale $L; Set-Culture $L; Set-WinHomeLocation -GeoId 46; $U = New-WinUserLanguageList $L; Set-WinUserLanguageList $U -Force ; Copy-UserInternationalSettingsToSystem -WelcomeScreen $True -NewUser $True ; shutdown /r /t 0

NOTE 1: es-CL is for Spanish (Chile), for other countries see here for references: https://learn.microsoft.com/dynamics365/business-central/dev-itpro/compliance/apptest-countries-and-translations#supported-languages

NOTE 2: GeoId 46 is for Chile in decimal, for other countries see here for references: https://learn.microsoft.com/windows/win32/intl/table-of-geographical-locations?redirectedfrom=MSDN

    I will add something that probably helped with fixing the issue - it's the "Fast startup" option in the Power Options, when you want to change the shutdown settings. Just uncheck the option "Turn on fast startup (recommended)" and it should do the work. When enabled, even when you restart or turn off and on the PC, it still seems to be working when you check for the up time in Task Manager.
