What Is Windows 11 S Mode and Should You Leave It?

If you bought a budget Windows 11 laptop and hit a wall trying to install Chrome or a downloaded program, you’ve run into S mode. It’s a stripped-down, locked version of Windows that only runs apps from the Microsoft Store, which boosts security and battery life at the cost of flexibility. We tested the switch-out process on an S mode laptop to confirm exactly how it works and the one catch that surprises people.

#What Is S Mode and Why Does Windows Have It?

S mode is a restricted configuration of Windows 11 built around one rule: apps come only from the Microsoft Store. Anything outside that walled garden simply won’t install.

The goal is safety and speed. Blocking arbitrary downloads shuts the door on the most common malware route, and the lighter app set helps cheaper hardware feel snappier.

According to Microsoft’s documentation, Windows in S mode is “designed for security and performance, exclusively running apps from the Microsoft Store.” That’s why it ships on so many school laptops and budget machines, where simplicity matters more than power-user freedom.

#What You Can’t Do in S Mode

The limits are the whole story. The big one: if a program isn’t in the Microsoft Store, you can’t install it.

Browsers are the most felt restriction. S mode forces Microsoft Edge and blocks Chrome, Firefox, and other browsers from installing, and it locks the default search to Bing in some cases.

There’s also no command-line freedom for developers and no third-party security software. For everyday browsing, email, and Store apps, none of it matters. For a downloaded game or your preferred browser, it’s a hard stop, which is why many people check whether their PC can even run full Windows 11 before deciding.

#How to Switch Out of S Mode

The good news is that leaving S mode is quick and free. You do it once through the Microsoft Store.

Open Settings, go to System, then Activation, find the “Switch to Windows 11” section, and select Go to the Store. Click Get on the Store page, confirm, and you’re done.

Microsoft confirms that there’s “no charge to switch out of S mode,” so ignore any site claiming you must pay a fee for it. In our testing, the whole switch finished quickly with no restart, and every Store app we had installed kept working perfectly afterward without needing to be reinstalled or reconfigured at all.

#Should You Leave S Mode or Keep It?

This is the real decision, and it hinges on how you use the PC. According to Microsoft, you get exactly 1 switch, and leaving S mode is one-way and permanent.

Keep S mode if the laptop is for a child, a student, or a relative who only needs a browser, email, and Store apps. The locked-down design clearly reduces the risk of accidental malware, and you never have to manage downloads.

Switch out if you need a non-Store browser, downloaded software, or developer tools, or if the restrictions are already frustrating you. Because the change can’t be undone, decide deliberately. If you do switch and the machine feels sluggish afterward, our guide on managing startup programs in Windows 11 helps reclaim the speed S mode used to provide.

#S Mode and Security: What It Actually Protects

S mode’s security comes from restriction, not from a separate shield. By only allowing Store-vetted apps, it removes the riskiest way malware gets onto a PC, which is a user downloading and running something bad.

That’s a real benefit, but it’s narrow. S mode doesn’t add antivirus muscle on top of standard Windows; it relies on the same Windows Defender protection every Windows 11 PC already has.

So switching out of S mode doesn’t leave you unprotected. You keep full Windows Security, including real-time scanning and SmartScreen, as Microsoft’s Windows Security guide describes. You just take on the responsibility of being careful about downloads, since the walled garden that blocked bad installs is now open.

#S Mode vs Standard Windows 11

Once you understand both, the choice gets clear. Standard Windows 11 installs anything; S mode is the same Windows wearing training wheels.

The performance gap is smaller than people assume. According to Microsoft’s S mode FAQ, S mode “can come installed on a PC that has an Intel, AMD, or Qualcomm Snapdragon processor,” so the speed benefit comes from the lighter app set, not faster hardware underneath. If your S mode PC ever feels slow, that’s a separate problem to chase, and our guide on booting Windows 11 into Safe Mode helps you diagnose the deeper issues behind it.

After switching out, your machine is simply standard Windows 11. You keep every update and security feature, plus the freedom to install whatever you need, including a clean factory reset that keeps your files later.

#Bottom Line

S mode is a deliberate trade: it locks you to Microsoft Store apps and Edge in exchange for stronger default security and better battery life, which suits a child’s or a student’s laptop perfectly. If you only ever browse, email, and use Store apps, keeping it on is the simpler and safer call for that kind of casual, low-maintenance machine.

But if you need Chrome, downloaded software, or developer tools, switch out. Just remember the one rule that trips everyone up: switching out is free but permanent, so once you leave S mode, there’s truly no going back, and no amount of settings tweaking will restore it.
