Entering 2026, discouraging figures for Windows 11 have emerged. Statcounter data from December 2025 reveals a continued decline in its market share, which fell by over three percentage points to 50.73%. This drop occurred despite the official end of support for Windows 10 in many global regions.
Conversely, Windows 10 experienced a resurgence, with its user share increasing from 42.7% to 44.68%. Even Windows 8 saw a rise in usage. The year 2025 proved challenging for Microsoft, marked by AI ventures that failed to gain traction and numerous inadequate Windows updates.
