Some older Windows versions still receive regular security updates, while others have already transitioned into maintenance mode. At the same time, interest in virtualization and emulation solutions is growing, as users seek to run legacy applications on modern systems. This trend impacts testing and development processes, especially when ensuring compatibility with legacy apps. How do you handle support for older Windows environments in your projects? Do you prefer virtualization, or do you rely on specialized tools? What experiences have you had with current update strategies?

In my last project, we used Docker-based Windows containers for Windows 7 applications because regular security updates are already in maintenance mode. This allowed us to test old DLL dependencies in isolation while automating the patch plan via WSUS for still-supported systems (e.g., Windows 10 LTSC).
