I have ran into a need to be able to switch languages in Vista quickly. Currently we are doing this by using a quad-boot system with 4 different locales of vista downloaded from MSDN, however we would LIKE (if possible) to be able to make these switches from within the same installation of Vista. Currently when in a different localized installation of Vista (German, for example) there is a drop down menu on the taskbar with text that says "DE". If I click this it allows for an option for "US English". However no changes seem to take place. Can anyone with experience with this shed some light ? This toggle switch on the taskbar looks promising, however doesn't seem to make any changes. If anyone knows how to quickly change the system-wide language (not just the keyboard set, or a few menus, the entire thing) please comment!
