As the financial services industry approaches the end-of-support dates for Windows 10, ATM operators face a daunting challenge of determining when and how to migrate their fleets from whatever version(s) of Windows 10 they have today over to wherever they want to wind up with the Windows 11 platform. While this may sound like a straightforward upgrade, the reality is far more complicated, nuanced, and potentially disruptive.
Most ATMs operating in the field today run a version of Windows 10 IoT LTSC (you folks out there still running Windows 7 or even Windows XP in the field know who you are), but not all versions of Windows 10 are created equal. Depending on the age of the ATM, the manufacturer, and the application stack, a single fleet may include one or more of the available versions:
Each version has its own support lifecycle, hardware compatibility, and upgrade path. This diversity complicates every aspect of operational planning, testing, and execution, especially when trying to maintain customer service levels, fleet availability standards, and industry compliance across a mixed fleet of machines.
Most problematic is the situation with Windows 10 IoT Enterprise LTSC/LTSB 2015, which reached the official end of its support life on October 14, 2025, and is no longer receiving security updates from Microsoft.
To further complicate this already complicated situation, the leading ATM manufacturers and software vendors are all at different stages of readiness when it comes to Windows 11. For example:
This lack of clarity and consistency means that every ATM deployer must carefully evaluate the status of their fleet to determine upgrade feasibility, timing, and cost.
Without proper planning, preparation, and testing resources in place, the actual migration to Windows 11 could easily become a logistical nightmare. Additionally, organizations that still rely on manual testing processes will find that managing all the changes and validating results across the different combinations of ATM hardware and software applications is a slow, error-prone, and resource-intensive exercise.
Paragon’s VirtualATM solution leverages virtualization and automation technologies, enabling ATM deployers to:
Whether you're validating screen flows, EMV processing, or host connectivity, VirtualATM provides the flexibility and scale needed to manage complex migrations with confidence.
The move to Windows 11 is inevitable, requiring careful planning and preparation – but it doesn’t need to become a project from hell. By recognizing the complexity of the current industry environment, developing a strategic response, and leveraging tools like VirtualATM, organizations can transform an otherwise risky and expensive upgrade into a strategic advantage over the competition.
We recognize that each fleet operator will need to develop their own unique strategy for dealing with the Windows 11 upgrade, along with all of the other projects, priorities, and possibilities that they must address. In this context of continual change, the value that a solution like VirtualATM can bring to an ATM operation cannot be overstated.
Companies that have already invested in modern testing tools and technologies will have a considerable advantage over those who have not. If your ATM operations still rely primarily on manual testing, it's past time for you to consider the advantages that ATM virtualization and automation can provide.
Faster execution, expanded test coverage, improved quality, increased control and collaboration, as well as remote access to the ATM test environment, will help your developers, testers, and QA resources manage a successful migration to Windows 11 and improve the overall efficiency of ATM testing operations.
