Hi, My Windows Update found it necessary to download KB3012997 (en-US_LP) for Windows 8.1 x64. But, I am using the Dutch version of Windows, so I do not know why it changed the language. In control panel I can not see a 'Change language' option. Also when searching for "Language" or "Taal"(=Language in Dutch) in the start menu I don't get anything At the 'View installed updates' section the language pack is also not listed. When searching in the Windows Start menu using the Dutch word for it, it still finds it, but when typing in English, it doesn't. Could someone please help me how to delete this language pack, since I prefer my Windows in Dutch instead of English. Never mind, I am stupid. You can uninstall languages also by using lpksetup.exe.
