Windows S mode is a restricted configuration of Windows that only allows Microsoft Store apps and limits default browser behavior. It is designed for security, predictable performance, and simpler management, especially on lower-cost or student-focused laptops.
This guide applies to Windows 10 and Windows 11 PCs that shipped with S mode enabled.
Does This Affect You?
If Windows blocks an installer from a website and mentions S mode, the PC is not broken. It is enforcing a software-source restriction. You can switch out for free, but the change cannot be reversed on the same installation.
What S Mode Restricts
- Apps must come from the Microsoft Store. Traditional downloaded .exe installers are blocked.
- Microsoft Edge remains the required default browser, and Bing is tied into the default search experience while in S mode.
- Command Prompt, PowerShell, and other tools may be limited because they can install or launch software outside the Store.
- The normal Windows interface and built-in apps remain. S mode is not a completely separate stripped-down operating system.
Check Whether the PC Is in S Mode
- Open Settings > System > About.
- Find Windows specifications.
- Look at Edition.
- If it says Windows 11 Home in S mode or similar, S mode is active. If “in S mode” is absent, your install issue has another cause.
Switch Out of S Mode
- Open Settings > System > Activation.
- Find Switch to Windows 11 Home or Switch to Windows 11 Pro, depending on the edition.
- Click Go to the Store.
- On the Microsoft Store page titled Switch out of S mode, click Get.
- Confirm the switch. It is free and usually completes within minutes.
- Check Settings > System > About again to confirm the “in S mode” text is gone.
Should You Leave S Mode?
The Security Benefit Is Real
Blocking traditional installers reduces exposure to malware, especially for children, students, shared PCs, and less experienced users.
Stay If Store Apps Are Enough
If everything you need is available from the Microsoft Store, staying in S mode is reasonable.
Switch Only When You Need Outside Software
Leaving S mode makes sense when you need a trusted app that is not available in the Store, such as a specific printer utility, business app, browser, or creative tool.
It Is Not a Paid Edition Upgrade
Switching out removes the restriction. It does not upgrade Home to Pro and does not cost money.
