This listing is for Windows 10 Enterprise LTSC 2021, a licence for 1 PC. It is the newest long-term servicing release in the Windows 10 family, built on Windows 10 version 21H2, and it has the longest support cycle of the three LTSC editions. Like the earlier ones, it receives security patches only and never new features.
How it compares with LTSC 2019 and 2016
- Most recent base. The 21H2 foundation gives the widest hardware compatibility of the three, including recent processors, NVMe, USB4 and modern graphics cards.
- Longest support window. Its patch deadline is the furthest away of the Windows 10 LTSC editions, which counts for equipment being deployed today.
What LTSC means in practice
- A fixed system. No feature updates, so the interface looks the same year after year.
- No Microsoft Store or built-in apps: no Photos, Mail, Xbox, widgets or suggested content.
- No preinstalled Microsoft Edge; install a browser separately if you need one.
- Enterprise features: BitLocker, AppLocker, Credential Guard, Application Guard, DirectAccess, BranchCache, Hyper-V, incoming Remote Desktop, domain join and Group Policy.
Who it is for
Industrial and medical machines, automation controllers, embedded systems, kiosks, digital signage and laboratories: places where stability matters more than novelty and certified business software needs an unchanged system. It is not the edition to pick for a general-purpose office PC.
