However, we haven’t seen that option appear, and there hasn’t been any official word from Microsoft-so don’t count on it.įor now, you can only get a PC in S Mode if the manufacturer placed it into S Mode at the factory, and if no one has taken it out of S Mode since. We’ve seen some rumors that Microsoft might place a “Switch to S Mode” option in Windows 10’s Redstone 5 update, allowing anyone to put any PC into S Mode.
