Approximately 16.9% of Windows client devices are still using Windows 10, while Windows 11 accounts for 78.8% of installations. Windows 10's market share has significantly declined from nearly 50% in mid-2025. The migration to Windows 11 is slowing, with remaining Windows 10 devices facing more complex and costly upgrade scenarios, including having three times as many active Common Vulnerabilities and Exposures (CVEs) compared to Windows 11. Legacy operating systems like Windows 7, Windows 8.1, and Windows XP are also factors in the migration challenges. Microsoft’s Extended Security Updates (ESU) program offers protection until October 2027 for consumers and until October 2028 for commercial customers.

Microsoft released update KB5099539 for Windows 10, enhancing security and addressing vulnerabilities. This update is part of a broader initiative for Windows 10 22H2, Windows 10 Enterprise LTSC 2021, and Windows 10 IoT Enterprise LTSC 2021. It will be automatically installed on eligible systems, resulting in build number 19045.7548. The update resolves issues in File Explorer related to OneDrive shortcuts and erroneous error messages during file deletions, as well as fixes for keyboard shortcut malfunctions. Windows 10 PCs will receive updated Secure Boot certificates, which are essential for system integrity, with Microsoft actively rolling these out. Secure Boot certificates for most Windows devices are set to expire starting in June 2026. Users must be enrolled in the Extended Security Updates (ESU) program to benefit from the KB5099539 update, which provides continued support until October 12, 2027.

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.

Microsoft has temporarily halted the rollout of the Windows 11 security updates for certain Dell devices due to reports of shutdowns and performance issues linked to the KB5101650 cumulative update. The issues began after the installation of the June 23, 2026, preview update (KB5095093), which caused a conflict with the Intel Innovation Platform Framework Processor Participant driver. Affected Dell systems are showing a yellow exclamation mark in Device Manager and may experience unexpected shutdowns, poor performance, increased heat, and battery drain. Microsoft is working with Dell to resolve the issue and will not distribute the KB5101650 update to impacted systems until a fix is implemented.
