I use Powerpoint 2010 on Windows 7. My keyboard layout is German, but I write my presentations in English.

Now I created a presentation with Default Language set to English, and I want it to use English for proofing. When I create a new slide/textbox/... the language is indeed English. However as soon as I start typing, the language changes to German. This happens because my system-wide keyboard layout is set to German. If keyboard layout is changed to English, everything is alright.

Now I want to stop Powerpoint from changing its proofing language to match my keyboard language. I tried changing the LangTuneUp key to Off or Prohibited in HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\LanguageResourcesas indicated here, but it didn't help. Any other ideas?

P.S. Oh how I hate it when application-developers try to be clever.

  • I'm grateful for this question, as I did not realize, that the problems I had with the proofing language in PowerPoint were driven by the keyboard language. Knowing that, I can switch my keyboard to English, when I work with PowerPoint and use this as a cumbersome workaround.

To disable Powerpoint from matching the system language (which fixes this very annoying behavior), go to Options->Language, then under Choose Display and Help Languages move "Match Microsoft Windows" and "Match Display Language" to the bottom of the list.

    Any update for Windows 10 + PowerPoint 2016? What if the new default for Display and Help Languages is the same as the Windows Language?

    This solution does not seem to work for me. I had it pretty low already and moving it to the end (and restating the application) did not resolve the problem.
