I was doing an analysis of my client's SharePoint 2010 server to view which language packs were installed.
I viewed the installed products and patches under
Central Administration -> Upgrade and Migration -> Check product and patch installation status
and only saw the English language pack listed.
I also checked the registry, just to be sure.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\14.0\WSS\InstalledLanguages\
The InstallLanguages
folder wasn't present, so I assumed the only language available was the language in which SharePoint 2010 was installed with (English).
From these findings, I would assume that no additional language packs were installed into this SharePoint 2010 server, however, I was confused when I saw several "Microsoft Office Server Proof 2010" installations in different languages.
Are these related to language packs? I'm about to install SP2 for SharePoint 2010, and I need to know if I need to install various Language Pack SP2 updates.
