Approximately 16.9 percent of monitored Windows devices are still running Windows 10, a decline from about half a year ago. Windows 10 will receive updates until October 12, 2027, for consumer devices and until October 10, 2028, for commercial customers. Small and medium-sized businesses (SMBs) have 21.4 percent of their machines on Windows 10, with 23 percent in healthcare and pharmaceutical sectors and 22.7 percent in consumer and retail. A Windows 10 device has an average of 1,903 active Common Vulnerabilities and Exposures (CVEs), compared to 652 on Windows 11. Only 14 percent of Windows 10 assets have Extended Security Updates (ESU) patches applied. Many devices are tied to vendor certifications that complicate upgrades, and the rising cost of new PC hardware is a concern. The stagnation of Windows 11 adoption continues, with minimal change in market share distribution.
