Plan language decision for TFS installation very carefully

Hearing this from customers a bunch of times now I want to point out, that you should carefully decide if you really want to use a localized TFS Version.
There is NO supported WAY to change the chosen TFS language after you have created Team Projects. (Before you can for sure uninstall and reinstall). Microsoft does not support changing TFS languages in any way!

If you e.g. install a German TFS and want to use the SCRUM Project Template you are already in trouble. SCRUM as well as most others 3rd Party process templates do not support a German TFS.

If you are not sure, put yourself on the safe side and install an English TFS.

To be clear: This is different for Team Suite and all other Client products here you can change language by simply uninstalling the old and installing the new language version, if you have a valid licence :-)
