No blog post can give you a static list that remains accurate forever because Microsoft releases updates constantly. To be the "best" engineer, you need the best tool.

Do not rely on forum posts from three years ago. Instead, use the official Siemens Product Compatibility Matrix:

This tool allows you to check if a specific Windows KB update or a specific version of SQL breaks compatibility with your version of WinCC.

| Operating System | Limitation | | :--- | :--- | | Windows 11 Pro/Enterprise | Not officially listed in the original release notes, but many users report success with WinCC Runtime Advanced. Not recommended for Server SCADA. | | Windows Server 2016 | Functions but lacks optimized driver stack for modern PLCs (S7-1500 R/H). |

WinCC relies heavily on Microsoft SQL Server for its historical data logging and tag archiving. WinCC 7.5 SP2 introduced support for newer SQL environments.

Important Note on SQL Express: For standalone stations or clients that do not require the full SQL Server engine, WinCC 7.5 SP2 supports SQL Server Express 2016, 2017, and 2019. However, be aware of the database size limitations inherent to the Express edition (typically 10GB max).

WinCC 7.5 SP2 Compatibility: The Ultimate Guide to Best Practices

Achieving a stable SCADA environment requires strict adherence to the SIMATIC WinCC V7.5 SP2 compatibility list. Operating outside these parameters often leads to SQL Server installation failures, runtime instability, or broken communication with PLCs. Core Operating System Support

WinCC V7.5 SP2 is designed primarily for 64-bit architectures. For a reliable setup, verify your OS version against the official WinCC Delivery Release. System Type Supported Operating Systems (64-bit only) Workstations

Windows 10 Professional & Enterprise, Windows 11 (see notes) LTSC Versions Windows 10 LTSB 2015/2016, LTSC 2019 Servers Windows Server 2012 R2, 2016, 2019

Note on Windows 11: While original V7.5 versions were not compatible, WinCC V7.5 SP2 and higher officially support Windows 11 Pro and Enterprise.

Server 2022: Official support generally begins with WinCC V7.5 SP3 or later versions like WinCC V8.0. Critical Software Requirements

Compatibility isn't just about the OS. WinCC relies on a specific ecosystem of middleware and database tools.

Microsoft SQL Server: WinCC V7.5 SP2 requires Microsoft SQL Server 2016 SP2 (64-bit). Using newer versions like SQL 2022 without an official service pack from Siemens can break project connections.

Virtualization: Siemens supports running WinCC on VMware ESXi (6.5, 6.7, 7.0) and Microsoft Hyper-V (2012 R2, 2016, 2019).

.NET Framework: Installation of the SQL Management Studio typically requires .NET Framework 3.5. Depending on your OS, you may also need versions 4.7 or 4.8. Hardware & Environment Best Practices

To prevent performance bottlenecks, follow the recommended hardware specifications rather than just the minimum requirements:
