I ran into this trying to set up a new Dell laptop for my mom. It shipped to her in "S mode", meaning that among other things I couldn't install arbitrary software from the web. I assumed there'd be some straightforward way to disable it (even if it might be a little buried to discourage normies). But after several hours of searching through tutorials and mucking about in Windows settings, the command prompt, BIOS, and even the system registry, and I flatly could not do it. Never seen anything like it before. Ended up wiping and replacing Windows with Linux Mint, which she was happy with.
