Applies To: Windows 7, Windows 8, Windows Server 2008 R2, Windows Server 2012, Windows Vista
Compatibility with Earlier Versions of MMC
MMC 3.0 is designed to support snap-ins designed for MMC 2.0 and MMC 1.2. You can add these snap-ins to an MMC 3.0 snap-in console, and they will function as they do in the versions of MMC for which they were designed.
You can use MMC 3.0 to open a snap-in console that was created using MMC 2.0 or MMC 1.2. If you then save the snap-in console, you will be asked whether to save it in MMC 3.0 format. If you save it in MMC 3.0 format, you will not be able to open it by using earlier versions of MMC. You cannot use MMC 2.0 or MMC 1.2 to open a snap-in console that was created using MMC 3.0.
