Microsoft reported its earnings for the fourth quarter of 2025 , ending December 31. During the earnings call, Microsoft highlighted that its Windows 11 operating system is achieving goals faster than its predecessor, Windows 10. As of today, Windows 11 has officially reached one billion global users. It took the new Windows OS just 1,576 days to reach this milestone, compared to the 1,706 days it took Windows 10. Microsoft CEO Satya Nadella stated that this is a significant milestone for the Windows operating system, which is now expanding more rapidly than during the days of Windows 10. With the recent end-of-life for Windows 10, many users and enterprises are looking to upgrade from their aging systems, and the logical choice for the next build is Windows 11.

Windows 11 has been on the market since October 5, 2021. In the tech space, that is a long time for any software product. Over time, it evolved from a slight reskin of the Windows 10 OS into a completely different user experience with more modern layouts and a modernized UI, but it also came with a slew of issues. As Microsoft has tried to integrate everything into a singular OS, issues became common with updates, causing random bugs and system crashes. Nowadays, it is popular to criticize Windows 11, but despite its buggy nature, the success and market penetration speak for themselves. Microsoft plans to keep Windows 11 as a long-running version, so it might be a while before we see a Windows 12 or anything similar.
