If your SharePoint 2010 farm has been running for a while and documentation, well let’s just assume that it doesn’t want to show up with a normal browse through your file server and you need to rebuilt this farm like yesterday.

And you have no idea whether you installed Chinese (Simplified) or Chinese (Traditional). Well do not fear. Registry is here to help

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\WSS\InstalledLanguages\<LCID>

here you will see something like this:

LCID – Reg_SZ – {language pack build level}

1033 – Reg_SZ – 12.0.4518.1000

1031 – Reg_SZ – 12.0.4518.1000

or

LCID – Reg_SZ – {language pack build level}

1033 – Reg_SZ – 12.0.6219.1000

1031 – Reg_SZ – 12.0.6219.1000
