Critical Note: WinCC 7.5 SP2 dropped support for several older OS versions. Attempting to force installation on Windows 7 or Windows Server 2008 will result in the installer blocking the setup or unpredictable behavior during archiving.
WinCC uses Microsoft SQL Server for process value archiving, alarm logging, and user administration. WinCC 7.5 SP2 still relies on a dedicated MS SQL instance (not the TIA Portal integrated one).
