What Is S Mode in Windows 11? Pros, Cons and Limits

What is S mode on Windows? It is a locked-down configuration of Windows 11 Home that only runs apps from the Microsoft Store, uses Microsoft Edge as the default browser and Bing as the default search engine. Microsoft designs it for security and simplicity. You can switch out of S mode for free from the Store, but the change is permanent.

What Is S Mode in Windows 11?

S mode is a restricted way of running Windows 11 Home, not a separate edition you buy. It ships on some budget laptops and education devices, and you'll see "Windows 11 Home in S mode" on the box or in Settings → System → About.

The idea is simple: if the PC can only install apps vetted through the Microsoft Store, it is much harder for malware disguised as a normal download to get in. That restriction is the whole feature. Underneath, it is the same Windows 11 with the same Windows 11 hardware requirements, the same updates and the same Settings app.

According to Microsoft's Windows 11 in S mode FAQ, S mode in Windows 11 is only available on the Home edition. Windows 10 offered Pro, Enterprise and Education in S mode, but those devices had to leave S mode before upgrading to Windows 11.

What Are the Limits of S Mode?

The main limit is that you can't install traditional desktop programs downloaded from the web. Everything else follows from that rule.

In practice, this rules out common tools such as Google Chrome installers from the web, many games launchers, printer utilities, VPN clients, older accounting software and the full desktop installers for some productivity suites. You can still visit any website in Edge and download other browsers that are listed in the Store, but you can't make them the default.

What Are the Pros and Cons of S Mode?

S mode trades flexibility for a smaller attack surface. Whether that is a good deal depends on who uses the PC.

Pros

• Lower malware risk, because unknown installers simply won't run.
• Fewer background programs, which helps low-spec laptops stay responsive.
• Simple to manage for children, older relatives or a shared family PC.
• Windows Security is built in, so there's nothing extra to install.

Cons

• Many everyday programs are not in the Microsoft Store.
• No choice of default browser or search engine.
• Limited third-party antivirus and peripheral software.
• No way to join a work domain or upgrade straight to Pro while in S mode.

How Do You Switch Out of S Mode?

You switch out through a free Microsoft Store page reached from the Activation settings. It takes a few minutes, needs a Microsoft account sign-in, and does not reinstall Windows or remove your files.

1. Open Settings → System → Activation.
2. Find the Switch to Windows 11 Pro section (the wording can vary slightly by device) and select Go to the Store.
3. Do not use the link under Upgrade your edition of Windows. That is a different process and keeps you in S mode.
4. On the Switch out of S mode page in the Microsoft Store, select Get.
5. Confirm when asked. You can now install apps from outside the Store.

If the option is blocked and the device belongs to a school or company, the organisation may be keeping it in S mode deliberately. Ask your administrator rather than trying to work around it.

Can You Go Back to S Mode After Switching?

No. Microsoft states that switching out of S mode is one-way, and there is no setting to turn it back on. A reset from Settings → System → Recovery keeps the PC on standard Windows 11 Home.

This matters for cause and effect: once the restriction is gone, protection depends on your own habits and security software. Keep Windows Security switched on, download only from developers' official sites, and consider whether you want extra protection. Our guide to the best antivirus for Windows 11 compares the built-in option with paid alternatives.

Should You Upgrade to Windows 11 Pro After Leaving S Mode?

Only if you need Pro features. Switching out of S mode leaves you on standard Windows 11 Home, which is fine for browsing, Office, streaming and most games.

Upgrade to Pro if you need BitLocker drive encryption, Remote Desktop hosting, Hyper-V virtual machines, Group Policy or joining a work domain. The reason is licensing: S mode blocks the in-place edition upgrade, so the order is fixed. First switch out of S mode, then enter a Pro key in Settings → System → Activation → Change product key. A Windows 11 Home to Pro upgrade key does this without reinstalling, and our step-by-step guide to upgrading Windows 11 Home to Pro covers the process. If you're still deciding, Windows 11 Home vs Pro sets out who benefits from each.

Windows 11 Education and Enterprise are a different matter: they are licensed through schools and volume licensing agreements, not sold as individual keys, and this store does not sell them.

A Common Mistake We See

Customers on a new S mode laptop sometimes buy a Pro key and go straight to Upgrade your edition of Windows. Microsoft notes that this route keeps the device in S mode, so they still can't install the software they bought the upgrade for. The key is fine; the order of steps is wrong.

Leave S mode first using the Go to the Store link, restart, then apply the Pro key. On Arm-based laptops with Snapdragon processors, also check that the desktop programs you rely on have Arm or compatible versions before you switch, because Microsoft notes specific app limitations on some Snapdragon devices.

Frequently Asked Questions

What's S mode on a laptop?

S mode is a setting on Windows 11 Home laptops that limits app installs to the Microsoft Store and fixes Edge and Bing as defaults. Manufacturers enable it on some budget and education models to improve security. Check Settings → System → About or Activation to see whether yours has it.

Is switching out of S mode free?

Yes. Microsoft does not charge to switch out of S mode. You complete it through a free Microsoft Store page reached from Settings → System → Activation. Your files and apps stay in place. Upgrading from Home to Pro afterwards is a separate step that needs a Pro licence.

Does switching out of S mode slow down my PC?

Switching out doesn't change Windows itself, so the PC runs the same immediately afterwards. Any slowdown comes from the programs you then install, especially ones that start with Windows or run in the background. Install only what you need and review startup apps in Task Manager.

Is S mode the same as Game Mode or efficiency mode?

No. S mode restricts which apps can be installed. Game Mode, in Settings → Gaming, prioritises games for system resources. Efficiency mode, in Task Manager, lowers a single app's priority to save power. The three features are unrelated, and turning one on or off doesn't affect the others.

Can I install Chrome in S mode?

Not from Google's website, because S mode blocks installers from outside the Microsoft Store. You can install browsers that are listed in the Store, but Edge remains the default. To make Chrome or another browser your default, you need to switch out of S mode permanently.

Do I need antivirus in S mode?

Microsoft recommends antivirus on every Windows device. In S mode, the built-in Windows Security is the option known to be compatible; third-party products work only if the vendor offers an S-mode version. After switching out, you can choose any Windows 11 compatible antivirus.

Conclusion

S mode on Windows 11 is a Store-only, Edge-only version of Home that suits children, shared PCs and light users. If you need software from the wider web, switch out for free, knowing it's permanent, and add Pro only if you need its business features.
