Browsers: While Internet Explorer 11 was the original standard, Microsoft Edge in "Internet Explorer Compatibility Mode" is now the recommended path for WebNavigator and DataMonitor. WinCC 7.5 Windows 11 - SiePortal - Siemens
I understand you're looking for the WinCC V7.5 SP2 compatibility list (likely "best" meaning most reliable or complete), and you want to develop a feature related to it. Let me clarify:
| Component | Recommended Version | Compatibility Notes |
| :--- | :--- | :--- |
| SQL Server Standard | 2017 (CU20 or higher) | Required for >5,000 archive tags. Use Latin1_General_CS_AS collation. |
| SQL Server Express | 2017 (SP1) | For small projects (<2,000 tags). Install before WinCC setup. |
| SQL Server Management Studio (SSMS) | 18.10 or 19.x | Essential for manual backups. Do not install on the same partition as WinCC database files. |
The keyword "wincc 75 sp2 compatibility list best" is search engine shorthand for a deeper engineering need: stability. After reviewing thousands of field reports and Siemens official matrixes, the absolute best configuration is: SIMATIC WinCC V7
Windows 10 Enterprise LTSC 2021 + SQL Server 2017 Standard + WinCC 7.5 SP2 Update 6 + CP 1623 + Siemens IPC hardware.
Avoid Windows 11, skip SQL 2019, and never auto-apply Windows security patches without testing. Use the antivirus exceptions list religiously. Perform weekly configuration tool backups.
By following this guide, your WinCC 7.5 SP2 system will achieve the mythical industrial status: "Installed and forgotten" – running for years without a single blue screen or database lock.

For SIMATIC WinCC V7.5 SP2, the best practice for ensuring compatibility is to use the official Siemens Compatibility Tool. This tool is the definitive source for released combinations of operating systems, database versions, and virus scanners. Core Software Compatibility
The following software versions are officially supported or included with WinCC V7.5 SP2: Operating Systems (64-bit):
Windows 10: Professional, Enterprise, LTSB 2015/2016, and LTSC 2019.
Windows 11: Supported specifically as of WinCC 7.5 SP2 (or version 8.0). Windows Server: 2012 R2, 2016, 2019, and 2022. Windows 10 Enterprise LTSC 2021 + SQL Server
Database: Microsoft SQL Server 2016 SP2 (64-bit) is required and typically included in the installation. It is not compatible with SQL Server 2022.
Browsers: Microsoft Internet Explorer V11.0 (32-bit) is required for online help. Microsoft Edge is released for WebNavigator/DataMonitor as of Update 1.

A SCADA system that cannot talk to the PLC is just a pretty slideshow. The compatibility list dedicates significant space to SIMATIC NET and channel drivers. For WinCC 7.5 SP2, the best-in-class configuration involves ensuring that the Industrial Ethernet (IE) driver version matches the firmware of your Siemens controllers (S7-1200/1500).
Crucially, the list clarifies which versions of OPC UA are supported. WinCC 7.5 SP2 introduced enhanced OPC UA client functionality, but it requires a specific patch level. The compatibility list shows that while basic OPC DA is supported, OPC UA certificates require Windows Server 2019’s specific security protocols. Ignoring this leads to "Certificate Untrusted" errors that halt data flow.
Furthermore, for users connecting to third-party PLCs (Rockwell, Modbus, etc.), the list identifies which Communications Channel DLLs are validated. A "best" practice is to avoid using generic TCP/IP sockets; instead, use the certified SIMATIC OPC Server listed in the compatibility matrix.
WinCC 7.5 SP2 is compatible with the following software:
| Model | Compatibility Grade | Why it’s best | | :--- | :--- | :--- | | SIMATIC IPC 427E (Box PC) | A+ | Pre-installed with WinCC RT-ready image. Fanless. | | SIMATIC IPC 477E (Panel PC) | A+ | Integrated multi-touch. Perfect for operator panels. | | SIMATIC IPC 647E (Rack PC) | A | High core count (up to 8) for heavy archiving. |
