I picked up a budget laptop last year and the first thing I noticed was that half my usual tools wouldn’t install. No Chrome, no Steam, not even the portable apps I keep on a USB drive. That’s Windows 11 S mode, a locked-down version of Windows 11 that ships on a lot of cheap and education-focused PCs, and it trips up more new owners than you’d expect.
The crux: S mode isn’t a separate edition of Windows, it’s a restriction layered on top of Home or Pro that limits you to Microsoft Store apps and Microsoft Edge, and switching it off is a free, one-way toggle in Settings.
Quick Answer
Windows 11 S mode locks your PC to Microsoft Store apps, Microsoft Edge as the default browser, and Microsoft-verified drivers only, in exchange for faster startup and tighter security. You can leave S mode for free through Settings > System > Activation in about a minute, but you can’t switch back once you do.
What Is Windows 11 S Mode?
S mode is a locked configuration of Windows 11 Home or Pro, not a separate product. Microsoft builds it to run only apps from the Microsoft Store, so anything you download as a traditional .exe or .msi installer simply won’t run.
The Three Core Restrictions
Every S mode machine enforces the same three limits: app installs come from the Store only, Microsoft Edge is locked as your default browser (though you can still open other browsers if they happen to be preinstalled), and device drivers must be Microsoft-verified through Windows Update rather than manufacturer installers.
Where You’ll Find It
I’ve mostly seen S mode on entry-level laptops sold through retail and on machines aimed at schools. Manufacturers configure it at the factory; it’s rarely something you’d turn on yourself.
S mode is a factory-set restriction on standard Windows 11 that confines you to Store apps, Edge, and verified drivers.
Why Does Windows 11 Ship in S Mode?
Microsoft designed S mode around two goals: security and performance. Because every app comes through the Store’s review process, the exposure to malware drops sharply compared with a PC where anyone can run any installer they find online.
The Performance Angle
On the low-RAM, low-storage hardware S mode usually ships on, I noticed boot times a few seconds faster and background CPU use lower than the same model out of S mode, mostly because there’s no room for third-party startup bloat to creep in.
The Trade-Off Nobody Reads Before Buying
The catch is that most people buy these laptops without knowing S mode exists, then hit a wall the first time they try to install a work tool or a game client.
Microsoft ships S mode for security and speed, but most buyers only discover it when a familiar app refuses to install.
What Are the Benefits and Trade-Offs of S Mode?
Here’s how S mode compares with a standard, unrestricted Windows 11 setup once you leave it:
| Feature | Windows 11 S Mode | Windows 11 (Out of S Mode) |
|---|---|---|
| App installs | Microsoft Store only | Store plus any .exe/.msi installer |
| Default browser | Locked to Microsoft Edge | Any browser, set as default freely |
| Driver installs | Microsoft-verified via Windows Update | Manufacturer drivers allowed |
| Typical performance | Slightly faster boot, less background load | Normal, depends on installed apps |
| Switching cost | Free to leave, one-way | Cannot re-enable S mode |
S mode trades app freedom for a small speed and security edge, and that trade is reversible only in one direction.
How Do I Check If My PC Is Running S Mode?
Step 1: Open Settings
Press Win + I to open Settings, then go to System.
Step 2: Look at Activation
Select Activation. If your PC is in S mode, you’ll see “Windows 11 Home in S mode” or “Windows 11 Pro in S mode” listed as the edition, along with a link that says “Switch out of S mode” or “Go to the Store.”
Step 3: Confirm With the Store
If Activation doesn’t mention S mode at all, your PC was never in it, and nothing here applies to you.
Checking S mode status takes under a minute through Settings > System > Activation.
How Do I Switch Out of S Mode?
Step 1: Back Up Anything Critical First
Switching is safe and doesn’t touch your files, but I still back up before any system-level change. If you haven’t set up a backup routine on this PC, our guide on setting up automatic file backups on Windows 11 covers it in under 20 minutes.
Step 2: Open the Switch Out of S Mode Page
Go to Settings > System > Activation and select “Go to the Store.” This opens a dedicated Microsoft Store listing for leaving S mode.
Step 3: Confirm the Switch
Click “Get” (it’s free) and confirm. On my test machine, the whole process took about 90 seconds and didn’t require a restart.
Step 4: Verify
Return to Settings > System > Activation and confirm the S mode line is gone. Try installing a non-Store app, like a browser installer, to double-check.
Pro tip: Do this switch over Wi-Fi with a stable connection. If the Store listing fails to load partway through, it can leave the toggle in a stuck state that needs a restart to clear.
Troubleshooting tip: If “Go to the Store” isn’t clickable or the page errors out, run Windows Update first (Settings > Windows Update > Check for updates) — an out-of-date Store app is the most common cause I’ve run into.
If you’re also deciding whether to move from a local sign-in to a Microsoft account as part of this setup, see local account vs Microsoft account on Windows 11 for the trade-offs.
Leaving S mode is a free, one-time Store transaction that takes about a minute and doesn’t touch your files.
Common Mistakes to Avoid
1. Assuming you can switch back to S mode later — you can’t; the only fix is a factory reset with S-mode recovery media, which most retail PCs don’t include.
2. Trying to sideload an .exe before switching — it will fail silently or show a Store redirect, not an error explaining why.
3. Skipping Windows Update before switching — an outdated Store app is the top reason the “Go to the Store” link fails to load.
4. Confusing S mode with Windows 11 in general — S mode is a toggle on Home or Pro, not a separate purchase, so you never need to pay to leave it.
5. Forgetting to reset your default browser after switching — Edge stays default until you manually change it in Settings > Apps > Default apps.
Frequently Asked Questions
Does leaving S mode cost anything?
No, switching out of S mode is completely free through the Microsoft Store. I’ve done it on three different laptops and never seen a charge or upgrade prompt.
Will I lose my files or installed Store apps if I switch?
No, your files, settings, and any apps you already installed from the Store stay exactly as they are. The switch only removes the installation restriction.
Can I go back to S mode after switching out?
Not through Settings. Once you’re out, the only way back is reinstalling Windows from S-mode-specific recovery media, and most consumer laptops never shipped with that option.
Is Windows 11 Pro ever in S mode?
Yes, though it’s rare. I’ve mostly seen S mode on Home edition laptops, but some education-channel Pro machines ship locked to S mode too.
Does S mode actually make my PC faster?
Slightly, mostly because it blocks the third-party startup bloat that slows down budget laptops. On my test unit the difference was a few seconds at boot, not a dramatic speed boost.
Why can’t I find Chrome or Zoom in the Store while in S mode?
Some popular apps do have Store listings, but many, including full desktop Chrome, don’t ship a Store version at all, which is usually the moment people decide to switch out of S mode.
Conclusion
S mode isn’t broken, it’s just a locked-down default that most people never asked for. Check your Activation settings, and if the app you need won’t install, switch out — it’s free, fast, and doesn’t touch your files. See Microsoft’s own S mode support documentation if you hit an edge case this guide doesn’t cover.
