On January 3, 2018, Microsoft released updates for its Windows operating systems to close the vulnerabilities which are grouped under the names Meltdown and Spectre.

The installation of these Microsoft updates has no effect on the operation of the S7-1500 Software Controller, irrespective of the version. These updates can therefore be installed on IPCs on which a software controller is being or is intended to be used.
