Windows 10 left support in October 2025. Business Extended Security Updates cost $61 a device in year one, $122 in year two (starting now) and $244 in year three, and they are cumulative. What to do with the PCs that still cannot move: replace, upgrade, virtualize, or put them behind a Cloud PC.
Windows 10 reached end of support on October 14, 2025. Organizations can buy Extended Security Updates through volume licensing for up to three years: $61 per device for the first year, doubling each year after. ESUs are cumulative, so a device joining in year two pays for year one as well.

Hardware that does not meet Windows 11's requirements, often in warehouses, labs and front desks.
Machines attached to equipment: a lab instrument, a CNC controller, a kiosk, where the vendor certified one OS.
Line-of-business applications that were never tested on Windows 11.
Office PCs on old hardware: replace them. Two years of ESUs ($183) is a large part of the price of a basic new PC.
Capable hardware: upgrade in place to Windows 11 after testing the line-of-business apps.
Apps that only run on Windows 10: deliver them from a Cloud PC or streamed application instead of local installs. Windows 10 Cloud PCs on Windows 365 are entitled to ESUs at no extra charge; on AWS, WorkSpaces Applications can stream the app to any device.
Equipment-attached machines: isolate them on their own network segment with no internet access, buy ESUs, and press the equipment vendor for a supported OS.
