How It Works:
- Get-CimInstance -ClassName Win32_OperatingSystem queries the operating system class, same as covered in earlier articles (build number, install date, architecture).
- MUILanguages returns an array of installed Multilingual User Interface (MUI) language packs - the language codes follow the standard format of language-region (e.g. en-US for English/United States, cs-CZ for Czech/Czech Republic).
- The first entry in the array is typically the primary display language currently in use, with any additional entries representing other installed language packs available to switch to.
