Add automatic dark mode in Microsoft Office

[VincentJoshuaET]

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\UI Theme value should just be also changed for automatic dark theme.

Thanks for the idea and providing me the right Registry Key.
Sadly Office always reverts this Value back to the UserConfig.
I set it to 4, I start word, it's dark. I close Word, reopen it, again white and the value is set to 0.
I could block access, but when users can't change the theme anymore in the apps itself. 😭

Well, what if you give us another option, so since user know that they'll lost access to change theme via apps itself, they will have an option to use it or not.

[Armin2208]

@xtprion your are smart lol

[VincentJoshuaET]

Any update on this?

[Armin2208]

I never did something

Are you considering to add this option with the warning mentioned above?

It was awesome if the office theme would change too. Maybe some more keys/code needs to be changed in order the theme will not only change but also stay till your app would change it again. What does the Office support say to this?? Can they help you (easily) implementing this function?

[udobehm]

Ok, I see. But thanks for investigating it!

Just donated. More coming if you find a solution for this.

[Armin2208]

@kcorax you know how life works haha

Can't wait for this to happen! For me it doesn't make much sense to you your auto-switcher until office is not switching along too (sorry).

Also, I think there are quite a lot who are using office, especially in the office! 😃

I'm afraid I've confirmed it's not possible though. Even if you intercept messages to the app. The only option would be to write directly in memmory like game trainers do, but that would be extremely fragile code. There's no point in encouraging a productivity app to crash for aesthetics.

Is there something in this powershell script that might help? I hacked away at the scheduled tasks in ADM and made something workable based on this, but I have to deal with a PS window popping up. It'd be better in-app if at all possible.
