Caution, not always German version

I had two computers (not my own) from XP to Windows 7 migration and have ordered for this Windows 7 media.
When I was vo place and I pushed the installation CD into the computer, I was quite amazed: As language only English selectable, although explicitly _deutsche_ version ordered (was also large DE on the envelope!
After studying the enclosed instructions I learned: In retrospect install German language package on CD bundled aja ...

I ended up with the GUI in German, however, the _deutsche_ version of the original software set adjourned etc. nciht with the still _englischen_ group and user names, as they are apparently named according to installation time.

Ie manually translate: Users -> Users, Authorized Users -> Authenticated Users, etc ...

Quite possible that in other SW still lurk other pitfalls.

My advice: If you ordered DE, but EN + language pack gets, then it sends back, because it is not what is advertised here!
