I've been very pleased with the performance of Microsoft Security Essentials and wanted to incorporate it in to SteadyState. Well it looks like application updates are now being covered in Windows Updates, but maybe not definition updates. So I wrote a simple batch file to have it launched using Custom Updates that is within Schedule Software Updates mseupdate.bat @echo off c: cd \Program Files\Microsoft Security Essentials MPCMDRUN.EXE -SignatureUpdate exit

Hi Barry, thank you for providing this script.
