Open an app. 

Click Maximize. 

Open another app. 

Click Maximize again.

If that's part of your daily Windows routine, Microsoft has added a simple setting that can eliminate those extra clicks.

Called "Open apps maximized," the new Windows 11 accessibility option automatically maximizes app windows when they open. 

Microsoft introduced it in the September 22, 2026 optional preview update, KB5124010, for Windows 11 versions 24H2, 25H2, and 26H2.

The feature is also part of the improvements carried forward into Microsoft's October 13, 2026 security update, KB5127648.

There's one catch. 

Microsoft is delivering Open apps maximized through a gradual rollout, which means it may reach different PCs at different times. 

Feature availability depends on the device and market.

For people who prefer working with a large app window, particularly on laptops or smaller displays, this is the kind of tiny Windows improvement that could quietly make everyday computing easier.

Here’s a Cool Tip: Let Windows maximize your apps automatically.

What Is Open Apps Maximized?

Open apps maximized is an accessibility setting that tells Windows 11 to automatically maximize application windows as they open.

Think about how often you open your browser, File Explorer, Word, Outlook, or another application and immediately click the Maximize button. 

If you almost always want your apps using the available workspace, Windows can now take care of that step.

Microsoft positions the feature as an accessibility improvement. 

It can reduce everyday friction for people who use a screen reader or magnification, work in tablet mode, or simply prefer a consistent larger workspace.

But you don't need to use accessibility tools to benefit. 

Anyone who routinely maximizes apps may find it useful.

That could include laptop owners working on smaller screens, older adults who prefer larger app windows, students concentrating on one application at a time, or business users who spend much of their day inside one primary program.

It isn't a dramatic Windows makeover. 

It's simply Windows remembering how you'd prefer your applications to open.

And sometimes that's exactly what makes a good Cool Tip.

What You’ll Gain

• Save clicks: Stop repeatedly pressing the Maximize button.
• See more: Start applications using more of the available workspace.
• Reduce window fuss: Spend less time resizing applications.
• Improve accessibility: Automatically use larger application windows.

Step-by-Step Instructions

Here's how to do it.

Windows 11

1. Open Settings.
2. Select Accessibility.
3. Select Visual effects.
4. Find Open apps maximized.
5. Turn Open apps maximized On.
6. Open an application to try the new behavior.

Try This

Suppose you open your browser every morning and immediately maximize it.

Turn on Open apps maximized and see whether Windows eliminates that extra step from your routine.

If the setting isn't listed under Visual effects, don't panic. 

These features are rolling out gradually, so availability can vary by device and market.

Pros and Cons

Pros:

• Fewer repetitive clicks: Especially useful if maximizing windows is already part of your routine.
• Easy to configure: Just one toggle under Accessibility.
• Accessibility benefit: Larger app windows may make applications easier for some people to use.
• Handy for laptops: Especially useful if you normally devote your screen to one application.
• Easy to reverse: Turn the setting off whenever you prefer traditional window behavior.

Cons:

• Less useful for multitaskers: If you intentionally arrange several smaller windows on the desktop, automatic maximization may not suit your workflow.
• Gradual rollout: You may not see the setting immediately, even on an updated PC.
• It's a convenience feature: Experienced users who rely heavily on Snap or carefully arranged windows may gain less from it.

Who Should Skip This?

You may want to leave the feature off if you regularly work with several application windows arranged across your screen.

For example, someone who keeps a browser on one side of the display and Word on the other may prefer Windows Snap and manual window controls.

Likewise, users with elaborate multi-monitor layouts may prefer picking the size and location of each application themselves.

This setting makes the most sense for people who find themselves reaching for Maximize almost every time they launch an app.

Troubleshooting and Limitations

Problem: Open apps maximized doesn't appear

• Why it happens: Microsoft is delivering the feature through a gradual rollout, and availability varies by device and market.
• Fix or workaround: Install current Windows updates, restart your PC, and check again later.

Problem: Your PC isn't current

• Why it happens: The feature is associated with Microsoft's recent Windows 11 servicing updates. KB5124010 applies to Windows 11 versions 24H2, 25H2, and 26H2.
• Fix or workaround: Open Settings > Windows Update and check for available updates.

Problem: You don't like apps opening maximized

• Why it happens: Automatic maximization simply may not suit the way you organize your desktop.
• Fix or workaround: Go back to Settings > Accessibility > Visual effects and turn Open apps maximized Off.

Feature Access

• Microsoft introduced Open apps maximized in the September 22, 2026 KB5124010 preview update for Windows 11 versions 24H2, 25H2, and 26H2. 
• The feature appears in Microsoft's Gradual rollout section, and availability depends on device and market.
• The October 13, 2026 KB5127648 security update applies to those same three Windows 11 versions and incorporates improvements from the September 22 KB5124010 update.
• One important warning for Windows 11 24H2 users: 24H2 Home and Pro reached the end of updates on October 13, 2026, and the October monthly security update is the last update available for those editions.
• Status: Currently rolling out. Availability varies by device and market.

Score

Criterion  |  Score (0–10)  |  Justification

Value  |  8

It eliminates a small but genuine annoyance for people who repeatedly maximize their apps.

Usability  |  9

Once available, it's controlled by a simple toggle in Windows Settings.

Wow Factor  |  5

Useful and overdue, but it's a convenience improvement rather than a major Windows change.

Total: 22/30  |  👍 Good

Open apps maximized is a classic Cool Tip: small, practical, easy to understand, and potentially useful every day.

It also complements Windows Snap nicely. 

Snap helps you arrange several windows, while Open apps maximized is aimed at people who prefer starting with a larger app window.

Key Takeaways

Windows 11's new Open apps maximized option eliminates a repetitive step for people who routinely enlarge applications immediately after opening them. 

Microsoft introduced it as an accessibility feature, but its simple convenience could appeal to almost anyone who prefers working with maximized windows.

Just remember that Microsoft is rolling out the setting gradually, so you may not see it immediately.
