On October 5, 2021, Microsoft officially launched the Windows 11 operating system. Eligible Windows 10 devices were given the opportunity to upgrade to Windows 11 free of charge, and at the same time, new pre-installed Windows 11 machines also made their way into the market. Although the hardware requirements, such as the necessity for TPM 2.0, sparked some controversies, Windows 11 still managed to capture the widespread attention of gamers and PC enthusiasts across the globe, thanks to its completely revamped design.

On the occasion of its 5th anniversary, Microsoft proudly announced that Windows 11 had amassed over 1 billion users. This remarkable feat was achieved in just 1,576 days, outpacing its predecessor, Windows 10, which took 1,706 days to reach the same milestone.

Over the past five years, Windows 11 has undergone numerous iterations and optimizations to enhance user experience. However, Microsoft's ambition to integrate an excessive number of features into the system has, at times, resulted in frequent issues during updates. These problems have ranged from random errors to system crashes, causing some inconvenience to users.

With the end-of-support date for Windows 10 approaching on October 14, 2025, Windows 11's market share has witnessed a significant surge. It now stands as the dominant operating system in the market. As a system version that Microsoft intends to support for the long haul, Windows 11 is poised to continue rolling out more updates. It will undoubtedly remain a focal point of interest for PC enthusiasts around the world.
