This can be a bit tricky. First, make sure your Windows is up to date. Sometimes, an update is required before you can switch out of S Mode. Go to Settings > Update & Security > Windows Update, and check for updates.
If everything is up to date, try these steps:
- Open the Microsoft Store and make sure you are signed in with your Microsoft account.
- Search for "Switch out of S Mode" in the Microsoft Store.
- Follow the prompts to switch out of S Mode. If you still get the error, try restarting your device and then try the process again.
