Hi,
The answer is in the post itself:
We're continuing to refine this experience and plan to expand it to more scenarios over time. We're beginning to roll this out to Windows Insiders, so it might not be available to everyone right away.
I am not able to get the Enable Math reading support of Narrator on the latest Experimental Build.

I have read the blog on the webpage: https://blogs.windows.com/windows-insider/2026/09/08/announcing-new-builds-for-8-september-2026/
After reading this I am curious about the MathML support of narrator. But when I installed the mentioned experimental version, I could not get the controls as well as the features mentioned for Narrator.
Could any one help me with this?

2026-09-16T03:23:26.17+00:00 Hello Sumit,
My Pc is on the Windows Insider build only as well on the required build as mentioned in the post. Is there any other way I can enable this?

2026-09-15T12:15:44.1733333+00:00 Math reading support is included in Windows 11 Insider Experimental Preview Build 26340.9354, but it is being rolled out gradually. That means it might not appear for every Insider immediately, even on the correct build.
Supported facts for this build:
- Math reading is available in Narrator on build 26340.9354.
- It works in supported Microsoft 365 apps, including Word and PowerPoint.
- To use it, turn on Narrator with Windows key + Ctrl + Enter and open a supported document that contains mathematical equations.
- For detailed equation navigation, press Narrator key + Alt + N to enter math navigation mode.
- Use the arrow keys to move through parts of the equation.
- Press Esc to exit math navigation mode.
- The feature requires no additional download or setup.
- The release notes also state that rollout has started, so it might not be available to everyone right away.
Because the device is already on OS build 26340.9354, the most likely reason the controls are missing is that this feature has not reached that device yet through the gradual rollout.
If testing is needed now, the valid checks are:
- Confirm the device is still on build 26340.9354 or later.
- Test in a supported app such as Word or PowerPoint with a document that contains math equations.
- Try the shortcut Narrator key + Alt + N while Narrator is running.
- Check Narrator settings for Math reading options, since the release notes say the experience can be personalized there.
- If it still does not appear, submit feedback in Feedback Hub (WIN + F) under Accessibility > Narrator.
