Windows Autopilot is now available with Surface, Lenovo, and Dell. Other OEM partners such as HP, Toshiba, Panasonic, and Fujitsu will support Autopilot in coming months. Check back here later for more information.

Windows 10 in S mode

Windows 10 in S mode is now available on both Windows 10 Home and Pro PCs, and commercial customers will be able to deploy Windows 10 Enterprise in S mode - by starting with Windows 10 Pro in S mode and then activating Windows 10 Enterprise on the computer.

Some additional information about Windows 10 in S mode:

  • Microsoft-verified. All of your applications are verified by Microsoft for security and performance.
  • Performance that lasts. Start-ups are quick, and S mode is built to keep them that way.
  • Choice and flexibility. Save your files to your favorite cloud, like OneDrive or DropBox, and access them from any device you choose. Browse the Microsoft Store for thousands of apps.
  • S mode, on a range of modern devices. Enjoy all the great Windows multi-tasking features, like snapping Windows, task view and virtual desktops on a range of S mode enabled devices.

If you want to switch out of S mode, you will be able to do so at no charge, regardless of edition. Once you switch out of S mode, you cannot switch back.
