READ MORE The reason that the Windows 10 spring 2021 update allegedly won't be a major one is that Microsoft has their attention focused elsewhere. It's widely-believed the Redmond-based firm is concentrating their efforts on two other major projects – the Windows 10 autumn update and the all-new Windows 10X operating system.

Windows 10X is a new version of Windows 10 that initially was only coming to dual-screen devices such as the Surface Neo, but is now also heading to single screen devices. Windows 10X is designed as a sleeker, more simple and quicker version of the OS that will act as a direct rival to the operating system found on Google's Chromebook range.
