Can the Windows update MS17-010 be installed on a system running WinCC OA?

As announed in an official statement by Microsoft Windows operating systems suffer from the ransomware known as "WannaCry".

The Microsoft Security Bulletin MS17-010 provides more details and bugfixes for the most common Microsoft operating systems, see the following link:

For the SIMATIC WinCC OA versions covered by the mainline support (at the moment 3.13 - 3.15)  we perform regular compatibility tests of Microsoft Windows Security Updates.

The security updates of MS17-010 have been successfully tested with WinCC OA 3.13, 3.14 and 3.15 together with the supported Windows versions (Windows 7/Server 2008 R2 and newer).

For details concerning the supported Windows versions please have a look at the WinCC OA documentation for every version.

We strongly recommend to install the Windows updates to ensure that the system is protected against the ransomware "WannaCry".
