Windows Hello Brightness Setting Is Coming: Your Screen Will Light Up Your Face in the Dark

The Windows Hello brightness setting is the newest low-light fix in Windows 11. If your face sign-in fails in a dim room, Windows can now turn your screen up for a moment so the camera sees you. It’s in an Insider test build, not a public release.

Microsoft announced it on October 16, 2026, alongside a small Xbox mode change for gamers.

Here are the quick facts:

• The brightness option is in the Experimental channel only, per a report on the announcement.
• It raises screen brightness only while facial recognition runs.
• The new gaming task view is in Beta build 26220.9739 and Experimental build 26340.9750.
• Nothing here has a public release date yet.

Treat all of it as a preview. Insider features can change or disappear before they reach everyone.

How the Windows Hello brightness setting works

Face sign-in uses an infrared camera, but plenty of laptops also lean on visible light, and a dark room can make scans fail. The new option brightens the display for a few seconds during the scan, then lets it go back to normal.

According to a news summary of the Insider announcement, the toggle is called “Automatically adjust screen brightness during facial recognition.” You’ll find it under Settings > Accounts > Sign-in options > Facial recognition (Windows Hello).

It’s a small idea, but it targets a real annoyance. Most of us have stared at a “Try again” prompt in a dark bedroom and ended up typing the PIN instead.

Which Insider builds have what

Microsoft shipped several builds on the same day, and the features don’t land everywhere. This table shows what the reports say.

The gaming change is described in the Experimental build notes as rolling out gradually. That means you may install the build and still not see it right away.

What the new Xbox mode task view changes

The second feature is a refreshed Gaming Task View in Xbox mode. It adds a navigation bar with quick buttons for Exit to Desktop and Power Options.

This matters if you use a Windows handheld or a PC hooked to a TV with a controller. Leaving a game used to mean hunting through menus. Now the two actions you want most sit in one bar.

If you run a handheld, it’s worth trying once you’re on a supported build.

Fix dark-room sign-in problems today

You don’t need an Insider build to make face sign-in more reliable. A few habits help on any Windows 11 PC.

• Turn on “Enhanced sign-in security” if your camera supports it, since it uses the infrared sensor rather than room light.
• Wipe the camera lens, because a smudge blurs the scan more than dim light does.
• Run “Improve recognition” in the Windows Hello settings and rescan your face, ideally once with glasses and once without.
• Keep a PIN set up as your backup sign-in.

Each of these takes under a minute. If scans still fail, a rescan in the room where you usually sign in is the best next step.

Should you try it now?

Only if you already run Insider builds on a spare or secondary PC. Experimental builds can break things, and rolling back later can mean a clean install.

If you’re on the stable release, there’s nothing to do yet. Keep your PC patched, and see our guide to Windows 11 26H2 for what’s rolling out to everyone. Our note on the KB5127648 security update covers what you should install first.

To check where you stand, open Settings > Windows Update > Windows Insider Program. Then see which channel your PC is in.

Frequently Asked Questions

What is the Windows Hello brightness setting?

It’s an option that briefly raises your screen brightness while Windows Hello scans your face in a dark room. It’s meant to cut failed sign-ins in low light.

Is the Windows Hello brightness option available to everyone?

No. Reports say it’s only in the Experimental Insider channel for now. Microsoft hasn’t announced a date for the public release.

Where do I turn it on?

Go to Settings > Accounts > Sign-in options > Facial recognition (Windows Hello). Look for the toggle about automatic screen brightness. It only appears on builds that include it.

Does the Xbox mode update need special hardware?

Microsoft’s notes don’t list any. It applies to the refreshed Gaming Task View in Xbox mode, and it rolls out gradually on the listed builds.

The bottom line

This is a modest but sensible update. Windows Hello has needed a low-light answer for years, and a short brightness boost is a cheap way to get one. Don’t install an Experimental build just for it, though. Wait for it to reach Release Preview, then check the setting after your next regular update.
