If you have wondered ever to use Windows Vista in Nepali Language, well the wait is now over. Microsoft has now published the official NEPALI Language Interface Pack (LIP) for Windows Vista that can be instantly applied to change the user interface. Do make sure that you have an English version of Windows Vista running as the NEPALI LIP can only be applied on such.

The following image album will give you a general idea of how your Windows Vista will appear after applying NEPALI LIP -
