Enable or Disable High Contrast Warning Message, Sound in Windows 10

In this post, you will see how to enable or disable High Contrast Theme Warning Message and Sound on your Windows 1o computer. This feature is specially designed to improve the usability criteria of the operating system and for the users having various health issues.

High Contrast Themes in Windows are useful for those computer users who have an eye-sight disability, since they heighten the color contrast of text, windows borders, and images on your screen, to make them more visible and easier to read and identify. When they are turned on or off, a warning message and sound is heard.

Enable or Disable High Contrast Warning Message & Sound

You can enable or disable high contrast theme’s warning message and sound using two different methods:

1. Through Control Panel
2. Using the Registry Editor app

Let us see both methods in details:

1] Through Control Panel

To enable the high contrast warning message and sound, follow these steps:

1. Open Control Panel.
2. Go to Ease of Access >  Ease of Access Centre.
3. Make the computer easier to see.
4. Check or uncheck “Display a warning message when turning a setting on”.
5. Again, check or uncheck “Make a sound when turning a setting on or off”.
6. Click Apply > OK.

Let’s now see them in detail.

First of all, open the Control Panel. To do this, click on the Start button, type Control Panel, and select the result from the top of the list.

In the Control Panel window, make sure the View is set to the Category.

Then click on Ease of Access > Ease of Access Centre.

Under the High Contrast section, check the checkbox next to the Display a warning message when turning a setting on.

After that, check the box saying Make a sound when turning a setting on or off.

Once you complete the instructions, close the window and you’re done.

If you want to disable the high contrast message and sound, then simply uncheck both boxes saying:

• Display a warning message when turning a setting on
