Windows 10 powers over two in five active desktops globally, holding a 42.7% share, while Windows 11 has 53.7% of active Windows desktops as of November 2025. Many enterprises are delaying upgrades to Windows 11 by using Extended Security Updates due to reliance on legacy applications and equipment lacking driver support. Funding for large-scale computer replacements is often unallocated, with migration costs including compatibility testing, deployment planning, retraining, and workflow management. The adoption rate of Windows 11 is lagging behind previous cycles, with Dell executives noting double-digit margins in this delay. Many consumers continue using older Windows 10 machines for secondary tasks, prolonging their lifespan. In some European regions, consumers receive free security updates for Windows 10, reducing the urgency to upgrade. The growth of Windows 11 reflects net additions rather than outright replacements, as operational advantages over Windows 10 remain limited.
