Overview

• As of October 14, 2025, Windows 10 no longer receives routine security fixes or technical support, though PCs continue to operate.
• Microsoft’s Extended Security Updates program is now open to consumers for one year, with enrollment via Settings > Update & Security > Windows Update using options that include a $30 fee, 1,000 Microsoft Rewards points, or a free path tied to Windows Backup and a Microsoft account.
• Users in the European Economic Area can enroll in ESU at no cost without mandatory cloud synchronization, while enterprises can buy up to three years of ESUs and certain LTSC editions remain supported into 2026–2029.
• Estimates suggest roughly one‑third of Windows PCs still run Windows 10—around 400 million by some analyses—with Valve’s latest survey showing about 32% of Steam users on the OS, though third‑party metrics vary.
• Security analysts describe a growing “security cliff” for unpatched devices, cautioning about ransomware, zero‑days, and scams as Windows 11’s stricter hardware requirements leave many older PCs without a straightforward upgrade path.
