Okay, if I were to switch out of S mode (which I know cannot be undone) and I enable the other security stuff will this mess up my apps like Microsoft word or Microsoft PowerPoint? I use them for college.
Hello again, EmK_11
You can switch out of S mode (simply search for "Switch" in the Store to find the setting and link to the Store to switch).
To answer your question, you can run trusted apps like Edge, Word, and Powerpoint (as well as other trusted apps like Spotify, Minecraft, iTunes, and many, many others). These apps work whether or not your PC is in S mode because they are trusted and verified apps. S mode only prevents the installation of unverified apps, for security.
