Windows 10 is designed to provide a common user interface for different systems. These include desktop, laptop, and all-in-one PCs, tablet computers, smartphones, and embedded systems such as the Xbox game console. This allows each type of system to run similar programs with greater ease. It has received mostly positive reviews.

Unlike earlier versions of Windows, Windows 10 is regularly updated with new features based on user feedback, including before it was first released. This is a part of a model of delivery known as software as a service. Every half a year, Microsoft releases updates with new features. Each release has a four-digit build number (a type of version number). The first two digits refer to the year of release, and the other two digits refer to the month of release (e.g. "1903" refers to a build released in March 2019).

New or returned featuresEdit
