Microsoft's November Windows 10 Patch Arrives With Fixes, Costs, and Another Nudge Toward Windows 11
Big Tech drops security updates for the OS it stopped supporting the way it used to, while businesses face rising fees and users get steered toward "cloud" accounts.
Microsoft released the Windows 10 KB5131096 extended security update on November 10, 2026. The package brings systems to build 19045.7846 for regular Windows 10 and 19044.7846 for Enterprise LTSC 2021. It rolls in the November Patch Tuesday fixes covering 1,235 vulnerabilities across Microsoft products, including one Outlook zero-day already under active attack.
The update also patches specific problems. It corrects an error that blocked adding printers published in Active Directory through Settings. It fixes Remote Desktop issues involving Intune certificate policies and shadow connections on older Windows Server versions. PowerShell script signing now requires stricter UTF-8 encoding checks, so some previously accepted scripts may need re-saving and re-signing. Cuba’s daylight saving time rules get adjusted for an extended period. Remaining USB audio problems from September updates are resolved.
These changes matter only for machines enrolled in the Extended Security Updates program or running certain long-term servicing editions. Mainstream free support for Windows 10 ended on October 14, 2025. After that date, ordinary Home and Pro systems receive no further security patches unless owners enroll in ESU.
For businesses the costs climb quickly. Year 1 ran at $61 per device. Year 2 doubles to $122 per device through October 2027. Year 3 doubles again to $244. Organizations that skipped earlier years must pay the cumulative amounts to catch up. Consumer options can be free if users sign in with a Microsoft account and back up settings, redeem Rewards points, or pay a one-time $30 fee that covers up to ten devices. European users face slightly different rules but still need an account in most cases. Microsoft extended consumer coverage quietly through October 12, 2027.
Millions of PCs still run Windows 10 more than a year after free support stopped. Market trackers put its share in the mid-to-high 20 percent range among Windows desktops. Many owners prefer the familiar system or own hardware that fails Windows 11’s requirements. Others simply resist being pushed onto a newer platform that adds more cloud features, telemetry, and account requirements.
The pattern is clear: A dominant software company ends free security support, then sells it back at rising prices while steering customers toward its cloud services and next operating system. Security patches remain necessary. The terms attached to them illustrate how control concentrates when one company supplies the operating system used by most businesses and households. Users and organizations now weigh the immediate cost of ESU against the longer-term expense and constraints of upgrading hardware and software on Microsoft’s timetable.
