Customize Closed Captions in Windows 10

Starting with Windows 10 version 1803, code name "Redstone 4", you can change the options for the "Closed captions" feature. Closed captions in Windows 10 will allow reading the words spoken in a video, TV show, or a movie. The feature has a number of options you can customize.

To change options for the Closed Captions feature, you can use Settings or Registry. We will review both methods.

To customize Closed Captions in Windows 10, do the following.

  1. Open the Settings app. Windows 10 Creators Update Settings 15019
  2. Go to Ease of access -> Closed Captions. Customize Closed Captions
  3. On the right, change the caption font, caption background, and dim window content settings to the desired values.

Alternatively, you apply a Registry tweak.

Customize Closed Captions using Registry Editor

It is possible to change the Closed Captions options using a Registry tweak. It can be useful when you need to export them to a Registry file and apply to another Windows 10 instance or copy to another computer.

  1. Open the Registry Editor app.
  2. Go to the following Registry key.
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ClosedCaptioning

    The option is there in fall creators update version 1709 but you said “Starting with Windows 10 version 1803, code name “Redstone 4”, you can change the options for the “Closed captions” feature”

    It seems that changing setting on “Caption Effects” in “Change Caption Font” section doesn’t do anything to the subtitle. No drop shadow, no uniform effect whatsoever since Creators Update version. Changing value in registry gave the same outcome. Already sent feedback on Feedback Hub but nothing happened. Nothing… Sigh!
