hello
please I want to know how to switch back to s mode or know if with this mode my pc is exposed, venerable.
Hi there wpclem,
There is no way to switch back to S mode, but rest assured that you can enable many of its security protections to keep your PC safe. First, go to Windows Security > App & browser control, and enable the available settings there, including Reputation-based protection which protects your PC from unrecognized apps online. You can also check to ensure you have security features like Memory integrity enabled: Windows Security > Device security > Core isolation > Core isolation details > Memory integrity (On).
