Tips: For peace of mind, we recommend that before you upgrade to Windows 10 you use the Get Windows 10 app to do a compatibility check. Many devices already have the app installed through updates. To see if you already have the app, look for the Windows icon on the far-right side of your taskbar. If you see it, select it to get started.
