Microsoft gets prepared to launch Windows 11 to the first wave of eligible devices, and also the release of the operating system certainly comes just in the right time.

It is because Windows has declined at least 4.9 points this past year, according to market share data put together by GeekWire based on IDC numbers.

Windows was running on just 80.5 percent of the devices out there in 2020, down from 85.4 percent a year before.

Microsoft is betting big on Windows 11 in rapid and in the long term, as the company expects the new operating-system also to produce a boost of sales for new computers. Windows 11 includes updated system requirements, and Microsoft recommends users to buy a brand new PC to make the the majority of the new OS.

Chrome OS the runner-up

"Since the first day of developing Windows 11, we've been working closely with this hardware and silicon partners for seamless integration across software and hardware. That co-engineering begins with innovation in the silicon," Microsoft said.

"From AMD and the incredible graphics depth through the Ryzen processors to the incredible performance of Intel's 11th gen and Evo Processors, to Qualcomm's AI prowess, 5G and Arm support, the innovation in our silicon partners brings together the best of Windows 11 using the largest hardware ecosystem on the planet. And with Dell, HP, Lenovo, Samsung, Surface and others, we've worked to ensure most PCs you can buy today is going to be ready for Windows 11 - across a variety of form factors and value points."

While Windows continues to be the best choice within the OS market, macOS has dropped to 3rd place despite its 0.8 points increase. In 2020, 7.Five percent from the devices available were running macOS.

The runner-up at this time is Chrome OS, that is powering 10.8 percent from the devices currently on the market, as sales of Chromebooks jumped substantially last year due to the global health issue.
