Last year, Microsoft announced that they are working on turning Windows into a more modular operating system, a vision that has been codenamed “Windows Core OS.” Windows Core OS which will eventually be the future basis for all forms of Windows 10 is designed to provide flexibility that creates a versatile and an excellent new Windows experience for multiple device-form factors. One such example is “Andromeda OS”, which is for the mobile version that will be installed on two-screen folding devices such as Surface Phone, operated primarily with the use of stylus. Apparently, Microsoft is now working onto build a brand new version of Windows 10 for PC devices like desktop computers, laptops and 2-in-1’s that is entirely built on UWP (Universal Windows Platform), making it the company’s first truly modern Windows OS for the traditional PC form factor, reports Windows Central. Codenamed as “Polaris”, this OS will eliminate old legacy components that have been part of the operating system for decades and are slowing it down. Polaris aims to create a much lighter software platform with less equipment loading, and thus lower power consumption. This system would also have a noticeably faster effect. Microsoft is already developing an extensible and adaptable shell, known as CShell, to serve as the basis for the user interface of Polaris, Andromeda and Windows Core OS. This interface found in Polaris is supposed to build the wall of Andromeda OS and Windows Core OS. It is worth emphasizing that Polaris will not get the native support of the Win32 application, as it will be replaced with UWP applications. However, Microsoft is considering the possibility of providing Win32 software support, but only through remote virtualization, suggest Windows Central’s sources. Existing Windows users will not be able to switch to Polaris, either through an update or through a clean installation. This means that you cannot switch from Polaris to Windows 10 Pro or vice versa. Polaris will only be available on the devices that come with it. Also, it is important to note that the currently available Windows 10 OS is not meant to be succeeded or substituted by Polaris. It is just a separate offer for those users looking for portability and a lightweight operating system. It is assumed that Polaris will be ready for release in 2019.
