By November 2025, Windows 11 held 53.7 percent of the Windows desktop market, while Windows 10 had 42.7 percent. Statcounter's data is based on a sample of around 1.5 million websites. Many consumers have devices incompatible with upgrades or prefer not to change functioning systems. In the EU, consumers benefit from free Microsoft Extended Security Updates (ESU). Businesses face slow change management processes due to poor planning and resource challenges. Organizations use ESUs to maintain security during transitions, but costs can be burdensome for unprepared businesses. Consumers often retain older Windows 10 machines for secondary tasks, affecting usage statistics. Organizations strategically leverage ESUs for mission-critical systems and budget constraints. The cost of ESUs is often less than the potential disruptions from migration. Windows 11 lacks compelling features to prompt enterprises to upgrade, and adoption is slower than previous operating systems, lagging by 10-12 points according to Dell's COO.
