Windows® 10 IoT Enterprise 2021 LTSC (ESD)

Windows 10 IoT Enterprise 2021 LTSC (ESD) is a specialized version of the operating system designed for critical, fixed-purpose devices, such as ATMs, production line controllers, medical equipment, digital displays, or POS terminals.

The acronym LTSC stands for "Long-Term Servicing Channel," while ESD (Electronic Software Delivery) refers to a digital method of license distribution—the purchaser receives an electronic activation key (ePKEA) rather than physical packaging, which allows for the rapid preparation of devices for deployment.

Key benefits of Windows 10 IoT Enterprise 2021 LTSC 

• Guaranteed 10-year support. Unlike standard versions of Windows 10—for which support is already coming to an end—this specific IoT 2021 LTSC version is officially supported by Microsoft until November 2031. Throughout this period, devices will receive critical security updates and patches.
• No forced functional updates. The system receives only security updates. New Windows features—which could alter the user interface or cause compatibility issues with your industrial software—will never be automatically installed. Device operation remains 100% predictable.
• A clean OS, free from unwanted software ("bloatware"). This version comes without any consumer-oriented entertainment applications: there is no Microsoft Store, Xbox, Cortana, games, or promotional links in the Start menu. As a result, the system consumes less RAM, occupies less disk space, and runs significantly faster.
• Advanced device lockdown features. The system includes a comprehensive suite of industrial tools that allow for complete control over the user environment:
  • The Unified Write Filter (UWF) makes the operating system "imperishable." When this filter is enabled, any changes made by the user, downloaded files, or even viruses are written only to temporary memory. Upon restarting the device, the system reverts to its pristine, original state.
  • Assigned Access (Kiosk Mode) allows you to configure a device so that, upon startup, only one specific application of your choice launches, while the user has no access to the Windows environment or settings.
  • Unbranded Boot enables you to hide all Windows loading logos or error messages and replace them with your company’s branding.
• Lower hardware requirements (compared to Windows 11). If your existing hardware does not meet the strict requirements of Windows 11—for instance, if it lacks a TPM 2.0 module or uses an older-generation processor—Windows 10 IoT 2021 LTSC serves as an excellent alternative. It is compatible with significantly older and less powerful processors while still providing a modern level of security.
