Windows 11 is Microsoft’s most advanced and modern operating system, known for its smooth design, fast performance, and improved security features. One special version of Windows 11 is called Windows 11 in S Mode. It is designed for people who prefer security, speed, and simplicity over flexibility. S Mode allows you to install only Microsoft Store apps and ensures your system stays safe from malware and harmful programs.
However, many users turn off S Mode to install apps from other sources. Once you switch out of S Mode, you get full access to all apps, browsers, and features that a normal Windows 11 system offers. But later, some users realize they miss the safety and stability of S Mode and want to turn it back on. Unfortunately, Microsoft has made this process one-way. Once you switch out of S Mode, there is no direct option to enable it again from the system settings.
Even though you cannot turn it back on directly, there are still some ways to reinstall Windows 11 S Mode or use alternative methods to regain its benefits. In this complete guide, we will explain what S Mode is, its features, how it differs from normal Windows 11, why users turn it off, and how you can restore or reinstall it on your device.
What is Windows 11 S Mode?
Windows 11 in S Mode is a special edition of the Windows operating system designed for security and performance. It is a streamlined version that restricts you from installing apps outside of the Microsoft Store. It also enforces the use of Microsoft Edge as the default web browser.
This limitation helps protect your computer from malicious software, as all apps in the Microsoft Store are verified and safe to use. It also ensures your system remains fast and stable since fewer background processes run compared to a full Windows installation.
S Mode is commonly used in educational environments, shared computers, or low-end devices where speed and reliability are more important than flexibility. For example, students and professionals who only need to browse the web, use Microsoft Office, or attend online meetings can benefit greatly from S Mode.
Benefits of Using S Mode in Windows 11
Here are some major advantages of using Windows 11 in S Mode:
- Enhanced Security: Since you can only install apps from the Microsoft Store, there is almost no risk of downloading malware, ransomware, or viruses from untrusted sources.
- Better Performance: S Mode limits background apps and services, which helps your system boot faster and run more smoothly. It also uses less CPU and RAM.
- Longer Battery Life: For laptop users, fewer background processes mean less power consumption, which helps your battery last longer.
- Simpler User Experience: The system is straightforward and easy to manage. It’s ideal for users who do not want to deal with complicated settings or software installations.
- Automatic Security Updates: Windows 11 in S Mode automatically updates itself and the installed apps, keeping your system protected and up to date without user effort.
Limitations of S Mode
While S Mode provides several advantages, it also comes with limitations that may not suit everyone. Here are some of its major restrictions:
- You cannot install apps outside of the Microsoft Store.
- You cannot use browsers other than Microsoft Edge.
- You cannot use command-line tools or scripts.
- Many professional programs like Photoshop, Android emulators, or video editors are unavailable.
- You have limited customization options for system behavior.
For users who need full control, S Mode can feel restrictive, which is why many people decide to switch it off.
Difference Between Windows 11 S Mode and Regular Windows 11
To understand the contrast better, let’s compare both versions in key areas.
| Feature | Windows 11 S Mode | Regular Windows 11 |
|---|---|---|
| App installation | Only from Microsoft Store | From any source |
| Browser | Microsoft Edge only | Any browser |
| Security | Highly restricted | Flexible but depends on user |
| Performance | Lightweight and fast | Varies based on usage |
| Updates | Automatic and limited | Fully customizable |
| Customization | Minimal | Full control |
| Best for | Students, beginners, education | Professionals, developers, gamers |
From this comparison, you can clearly see that S Mode focuses on security and simplicity, while regular Windows provides full functionality and flexibility.
Why People Turn Off S Mode
There are several reasons why users disable S Mode:
- They want to install software from outside the Microsoft Store, such as Chrome, Firefox, VLC, or Adobe Acrobat.
- They want to use third-party drivers, developer tools, or scripts.
- They need to play games or run software that is not available in the Store.
- They want more customization and control over system settings.
- Some apps for work, school, or business might not be compatible with S Mode.
Switching out of S Mode removes all these restrictions and converts your system into a standard Windows 11 Home or Pro version.
Can You Turn S Mode Back On in Windows 11?
Here’s the truth: Once you switch out of S Mode, there is no official way to turn it back on through system settings. Microsoft has designed the change to be permanent. Once you switch, your system is permanently converted to the regular version of Windows 11.
However, there are still some indirect ways to get S Mode back. These include reinstalling Windows 11 Home in S Mode from a manufacturer recovery image, or performing a clean installation of Windows 11 S Mode if you have the correct ISO file. Let’s go through each option step by step.
Option 1: Restore Factory Settings to Return to S Mode
If your computer originally came with Windows 11 in S Mode, you may be able to restore it by using the manufacturer’s recovery tool. Most brands such as HP, Dell, Lenovo, ASUS, and Acer include a built-in recovery option to reinstall the original factory version of Windows.
Steps to Restore S Mode Using Recovery Options
- Backup Your Files
Before starting, make sure to save all your important files and documents to an external drive or cloud storage like OneDrive. The restoration process will erase everything from your system drive. - Open System Recovery
Go to Settings → System → Recovery → Advanced startup, then click Restart now. Alternatively, you can press and hold the Shift key while clicking Restart from the Start menu. - Access the Recovery Environment
Once your system restarts, select Troubleshoot → Reset this PC → Restore factory settings. - Choose to Reinstall Windows
Select the option to restore your computer to factory settings. If your device came with Windows 11 S Mode originally, this process should reinstall that version. - Wait for the Process to Finish
The installation may take some time depending on your system speed. Once it’s complete, your computer should restart and boot into Windows 11 S Mode again.
This method works only if your PC’s manufacturer provides the original recovery image with S Mode. If your computer didn’t ship with S Mode, you’ll need to use another method.
Option 2: Reinstall Windows 11 S Mode Using Manufacturer Tools
Different PC brands have their own utilities to restore or reinstall Windows S Mode. Below are a few examples:
- HP – HP Recovery Manager or HP Cloud Recovery Tool.
- Dell – SupportAssist OS Recovery or Dell OS Recovery Tool.
- Lenovo – Lenovo Digital Download Recovery Service.
- ASUS – MyASUS in WinRE or ASUS Cloud Recovery.
- Acer – Acer Care Center or Acer Recovery Management.
You can download these tools from the manufacturer’s official website using another computer, then create a recovery USB drive to reinstall Windows 11 S Mode.
Option 3: Clean Install Windows 11 Home in S Mode Using ISO
If you do not have recovery media, another option is to reinstall Windows 11 Home in S Mode manually using an ISO file. Microsoft occasionally provides such images to manufacturers or educational institutions, but they are not publicly listed on the main Windows download page.
However, some authorized resellers or OEMs may provide these files upon request.
Steps to Clean Install Windows 11 S Mode
- Create Installation Media: Download the Windows 11 Media Creation Tool or use an existing ISO file of Windows 11 Home in S Mode (if available). Use it to create a bootable USB drive with at least 8 GB of space.
- Boot from the USB Drive: Insert the USB drive into your computer and restart it. Press the appropriate boot key (like F12, F9, or Esc) to open the boot menu and select your USB device.
- Start Windows Setup: Follow the on-screen instructions to install Windows. Choose the correct edition, such as “Windows 11 Home in S Mode.”
- Format Your Drive (Optional): If you want a completely clean installation, delete the old system partition. Be careful, as this will erase all data.
- Complete Installation: Once the setup finishes, you’ll be prompted to sign in with your Microsoft account and complete the initial setup.
If the ISO you used includes S Mode, your system will now run Windows 11 Home in S Mode again.
Option 4: Contact Microsoft or OEM Support
If none of the above methods work, you can contact Microsoft Support or your PC manufacturer’s customer service. Provide your computer’s model number and explain that you want to reinstall Windows 11 S Mode. In many cases, they can provide you with a direct download link or a recovery image specific to your device.
Option 5: Buy a New License or Device with S Mode
For some users, especially those who purchased their computer with regular Windows 11 Home or Pro, the only way to get back S Mode is to buy a new license or device that comes with it preinstalled. Many budget laptops and student notebooks come with S Mode as the default configuration.
If you depend on the simplicity and protection of S Mode, purchasing a device with it already installed may be the most practical choice.
How to Check if You Are in S Mode
If you are unsure whether your computer is currently in S Mode, follow these steps:
- Open the Start menu and go to Settings.
- Click on System, then choose About.
- Under the “Windows specifications” section, look for the Edition field.
- If it says “Windows 11 Home in S Mode,” your system is currently using S Mode.
If it simply says “Windows 11 Home” or “Windows 11 Pro,” S Mode has been turned off.
Things to Consider Before Reinstalling S Mode
Reinstalling or restoring S Mode requires erasing your system or performing a clean installation. You should consider the following:
- Backup all personal files, photos, and documents.
- Make sure you have a reliable internet connection.
- Keep your Windows product key or digital license ready.
- Confirm that your manufacturer supports S Mode for your device model.
- Understand that restoring to factory settings will remove all installed apps and settings.
Final Thoughts
Windows 11 S Mode is a simple, secure, and lightweight environment that provides excellent performance for everyday tasks. It is perfect for students, professionals, or anyone who values security and ease of use. However, once you switch out of it, you lose its protection features permanently unless you reinstall the S Mode version.
If you need to go back to S Mode, your best options are restoring factory settings, reinstalling from recovery media, or contacting your manufacturer. If those methods are unavailable, you can still create a secure Windows environment by using built-in security features and responsible software management.
Before disabling S Mode in the future, consider whether you truly need apps outside the Microsoft Store. If your daily tasks can be done within S Mode, staying in it is a safer choice.
