Do you really need all of those language packs?

When you install Windows, depending on your locale, you naturally have a language pack applied to the image. For me, its en-us (or US English). Anytime I run an update installation, service pack install or hotfix, I need to have the binaries updated for not just the system binary but the localized payload as well.

If you don’t need the language packs on your machine, do yourself a favor and remove them. Especially if this is something you know you have on your systems and you haven't installed Service Pack 1 yet. It will save you disk space and headaches in the long run because you wont end up needing to service all of those files multiple times.



Nice read at TechNet.
