Microsoft is reportedly testing a low-cost operating system called Windows 10 Cloud. The new version of Windows 10 is intended to compete with the growing popularity of Google’s Chrome OS.

According to Mary Joe Foley of ZDNet, Windows 10 Cloud will be a simplified version of Windows 10 designed to run Microsoft’s universal apps available from the Windows Store. References to OS have begun to appear in the company’s Insider build for Windows 10. Operating can replace Windows RT, which was designed to work with ARM-based processors.

Microsoft is not directly talking about the existence of Windows 10 Cloud OS and it is not clear when the OS will be available to customers. Microsoft is currently planning to roll out Creator Update to Windows 10 in April, later this year. Microsoft has announced plans to bring Win32 apps to ARM processors this year. The company plans to make a full-fledged Windows 10 device powered by a Qualcomm Snapdragon 835 processor.
