As you may be aware, after our recent announcement regarding the Microsoft Anti-Malware Platform Update, the two stand-alone releases (KB2831312 and KB2831316) were temporarily removed from Microsoft Update on April 10. This was because of a detection logic issue that was discovered with the Windows Defender platform update made available to Windows 8 clients (see http://support.microsoft.com/kb/2781197). The Windows Defender update was being erroneously offered to clients that had the new FEP or SCEP platform updates applied, leading to installation failures of KB2781197 that were misleading as the update does not actually apply when FEP or SCEP have been updated to the latest platform.
