What operating systems are most commonly used in industrial computers?

Choosing the right operating system (OS) for industrial computers is crucial for the stability, performance, and security of industrial applications. In 2025, companies are focusing on high-reliability operating systems that can operate in harsh environments and support modern technologies such as AI, IoT, and industrial automation. Let's see which operating systems dominate this industry!

Windows IoT / Windows Embedded

Windows IoT (formerly Windows Embedded) is one of the most widely used solutions in industry. Editions like Windows 10 IoT Enterprise and Windows 11 IoT Enterprise offer:

✅ Support for modern interfaces and business apps
✅ Compatibility with a wide range of industrial hardware
✅ Security updates from Microsoft
✅ Integration with Azure cloud and AI solutions

Where does it work? In industrial automation, POS systems, terminals, and network devices.

Linux – flexibility and reliability

Linux is the number one choice for many companies that need a stable, open, and secure operating system. Popular distributions in industry include:

• Ubuntu Core – version optimized for IoT and industry
• Debian – stability and long-term support
• Yocto Project – systems dedicated to embedded solutions
• Red Hat Enterprise Linux (RHEL) – enterprise support and reliability

Advantages:

✅ Customizable to specific company needs
✅ Low susceptibility to viruses and cyberattacks

Applications: PLCs, IoT devices, AI systems, and robotics

RTOS – Real-time operating systems

In applications requiring ultra-fast response, e.g. in robot control or critical systems, RTOS (Real-Time Operating Systems) is used. Popular options include:

• FreeRTOS – lightweight and open-source
• QNX – used in automotive and aerospace
• VxWorks – very reliable, used at NASA

✅ Main Advantages:
✔️ Extreme stability
✔️ Low latency in data processing
✔️ High fault tolerance

Used in: Industrial automation, robotics, medical systems and autonomous vehicles

MacOS and Android in industry? 

Although MacOS is not popular in industrial computers, Android is gaining in importance. It is mainly used in:

• HMI terminals
• IoT systems
• Warehouse and logistics devices

Advantages of Android Industrial:
✅ Easy to use and fast application development
✅ Touchscreen support
✅ Low implementation costs

Summary

There is no single "best" operating system – the choice depends on the application:

✅ Windows IoT – for companies needing easy integration and Microsoft support
✅ Linux – for flexibility, security, and IoT systems
✅ RTOS – where every millisecond counts
✅ Android – for HMI devices and mobile solutions
