Hey there Mackenzielambert,
S mode offers a number of protections that are enabled by default, right out of the box. They include:
- A policy that ensures that only trusted apps from Microsoft or the Windows Store can run
- Recommended Windows and app defaults
- Credential protection from Windows Hello
- Memory Integrity protection that protects the Windows kernel from malware
S mode has settings like these to help ensure your Windows PC is safe and protected. But if you desire similar protections, you can enable all of these settings independently to reach a similar level of protections as long as your PC hardware supports them.
