If you are running Windows RT, your device won’t upgrade to Windows 10. Microsoft will have an update available in September 2015 that will improve the Start menu and lock screen. Check Windows Update on your Windows RT device to make sure it is ready to download the update when available.

Note: Windows RT 8.1 is a Windows-based operating system that is optimized for thin and light PCs that have extended battery life and are designed for life on the go. Windows RT 8.1 only runs built-in apps or apps that you download from the Windows Store. Windows Update automatically keeps your PC up to date and Windows Defender provides up-to-date virus and malware protection. For more information on Windows RT 8.1, click here.
