Windows 10 Enterprise LTSC 2021
Windows 10 Enterprise LTSC 2021 is the Long-Term Servicing Channel build of Windows 10 Enterprise — a specialised edition for deployments that must remain stable for years without feature updates. Based on the Windows 10 21H2 codebase and released in October 2021, it is the preferred choice for kiosks, point-of-sale terminals, industrial controllers, medical devices, and any managed environment where a fixed OS version is a compliance or operational requirement.
What LTSC means
LTSC stands for Long-Term Servicing Channel. Unlike standard Windows 10 Enterprise, which receives new features twice a year, LTSC 2021 receives no feature updates for the duration of its support lifecycle — only monthly security patches and critical fixes. This keeps the OS at a fixed, predictable state for the entire 10-year window.
- Released: October 5, 2021 (based on Windows 10 21H2)
- Mainstream support: active until 12 October 2026
- Extended support: 13 October 2031
- Total supported lifetime: 10 years from release
- Feature updates: none by design
- Architecture: 64-bit only — no 32-bit edition exists
Enterprise-exclusive features included
- AppLocker — restricts which applications users can run, based on publisher, path, or hash rules. Prevents unauthorised software installation across the fleet.
- Credential Guard — uses virtualisation-based security (VBS) to isolate domain credentials, making pass-the-hash and pass-the-ticket attacks significantly harder.
- DirectAccess — gives remote workers seamless, always-on connectivity to corporate resources without manual VPN sessions.
- Windows Defender Application Guard (WDAG) — opens untrusted websites and files in an isolated Hyper-V container, containing any threat before it reaches the host OS.
- BranchCache — caches content from remote servers at branch offices, reducing WAN bandwidth consumption.
- Windows Update for Business (WUfB) — lets IT defer and schedule quality updates centrally, avoiding disruptive auto-restarts.
- Microsoft Edge (Chromium) — pre-installed in LTSC 2021. The pre-installed consumer Teams application is not included.

Support lifecycle
Windows 10 Enterprise LTSC 2021 is currently in mainstream support, which runs until 12 October 2026. This means Microsoft continues to deliver both new security fixes and non-security updates under the standard support agreement. Extended support then continues until 13 October 2031, covering security patches only — no Extended Security Update (ESU) subscription is needed to remain covered during this period.
If you are still running Windows 10 Enterprise LTSC 2019, note that its mainstream support ended in January 2024. LTSC 2021 is the current active LTSC generation.

Frequently asked questions
What does LTSC mean?
LTSC stands for Long-Term Servicing Channel. It is a specialised Windows 10 Enterprise build that receives only security and critical patches — no new features, no twice-yearly feature updates. This makes it ideal for environments where OS stability over many years matters more than access to new Windows capabilities.
Is Windows 10 Enterprise LTSC 2021 still supported?
Yes — LTSC 2021 is currently in mainstream support, which runs until 12 October 2026. Extended support continues until 13 October 2031. No ESU subscription is required. This is an active, fully supported product.
Does LTSC 2021 receive feature updates?
No — by design. Feature updates are deliberately excluded from the LTSC channel. You receive monthly security patches and critical fixes, but the OS feature set is frozen at the Windows 10 21H2 baseline for the entire support lifecycle.
What is the difference between LTSC 2021 and standard Windows 10 Enterprise?
Both include all Enterprise security features (AppLocker, Credential Guard, DirectAccess, WDAG). The key differences: LTSC 2021 receives no feature updates, is 64-bit only, and has a longer active support window (through 2031). Standard Enterprise receives twice-yearly feature updates and is available in 32-bit and 64-bit.
What is the difference between LTSC 2021 and LTSC 2019?
LTSC 2021 is based on Windows 10 21H2 (released October 2021) and includes Microsoft Edge Chromium. LTSC 2019 is based on Windows 10 1809 (released November 2018) and does not include Edge Chromium. Mainstream support for LTSC 2019 ended in January 2024.
Is LTSC 2021 available in 32-bit?
No. Windows 10 Enterprise LTSC 2021 is a 64-bit-only edition. No 32-bit build exists for this release.
Does LTSC 2021 include Microsoft Teams?
No. The pre-installed consumer Teams application is not bundled with LTSC 2021. Microsoft Edge (Chromium) is included — an improvement over LTSC 2019, which did not include it.
Is this a one-time purchase?
Yes. This is a perpetual digital licence — you pay once and own the right to use Windows 10 Enterprise LTSC 2021 with no ongoing subscription.
