Hi all
MS is gradually rolling out missing languages for W7 both in X86and X-64 bit versions.
The WELSH and ICELANDIC language packs have now been released - note to install these you must have the ENGLISH language Base Windows 7 product.
There's also a lot more languages released as well such as Norwegian, Persian (Farsi) etc etc. -- details on the site - just scroll further down.
Icelandic, Welsh Windows 7 Language Interface Packs now available | The Windows Club
Cheers
