Understanding Windows 10 LTSB and LTSC on Elo Touchcomputers & POS Systems
Audience: Public / Elo Customers, IT Administrators, Solution Architects & Integrators
Article Type: Operating System Overview & Architecture Guide
Many Elo Windows All-in-One (AiO) Touchcomputers and POS systems ship factory-imaged with specialized enterprise editions of Windows 10 known as LTSB or LTSC.
What Are LTSB and LTSC?
- LTSB (Long-Term Servicing Branch): The original naming convention used by Microsoft for specialized Windows 10 Enterprise releases (e.g., Windows 10 LTSB 2015, LTSB 2016).
- LTSC (Long-Term Servicing Channel): The modern naming convention adopted by Microsoft starting with Windows 10 Enterprise LTSC 2019 and LTSC 2021.
For detailed Microsoft documentation, see: Microsoft Learn: Overview of Windows Long-Term Servicing Channel (LTSC).
Intended Purpose & Mission-Critical Stability
LTSB/LTSC editions are purpose-built for specialized fixed-function appliances—such as Point-of-Sale (POS) registers, interactive kiosks, digital signage, medical devices, and manufacturing automation—where maximum operating stability is required and runtime software changes are strictly controlled.
How LTSC Differs from Windows 10 Home and Pro
To eliminate background disruptions and minimize system footprint, LTSB/LTSC releases omit consumer Universal Windows Platform (UWP) apps and non-essential background services:
| Component / Feature | Status in Windows 10 LTSB / LTSC |
|---|---|
| Microsoft Store | Not Included: Cannot be added or enabled. |
| Consumer UWP Apps | Omitted: No built-in Mail, Calendar, Xbox, Weather, News, or Groove Music apps. |
| Voice Assistant (Cortana) | Disabled / Omitted: Excluded from the system image. |
| Default Web Browser | Legacy images include Internet Explorer; standalone modern browsers (Chrome, Edge Enterprise standalone) can be deployed manually. |
Servicing Model, Security Patches & Upgrade Restrictions
- Security Maintenance: LTSC releases receive monthly quality, bug fix, and critical security patches through Windows Update for up to 10 years of extended lifecycle support.
- No Feature Upgrades: Unlike Windows 10 Pro (which receives periodic annual feature updates that alter OS builds), LTSC builds never receive automatic feature updates that could disrupt enterprise application compatibility.
- Licensing Policy: Microsoft licensing prevents direct in-place feature upgrades between major LTSC release branches without procuring a new OS license.
