Tridium; and

The update also provides a link to a general WannaCry support document from Siemens Healthineers. This document and a further linked Siemens’ blog post provides a good technical discussion of the WannaCry problem and solutions; including links to Microsoft updates for ‘unsupported’ (outdated?) Windows operating systems still in use by Siemens Healthineer (and too many other industrial control) products.
