HOWTO: Programatically Tell What VM Version Is Installed

• Microsoft Win32 Virtual Machine

SUMMARY

This article illustrates how to programatically determine what version of the Microsoft virtual machine (Microsoft VM) is installed on the system.

MORE INFORMATION

To programatically retrieve the version information for the Microsoft VM, you can use the SystemVersionManager.getVMVersion() static method in com.ms.util package. This method returns a Properties object that contains the Microsoft VM version data.

The code-snippet below illustrates how to get the version information of the Microsoft VM from your Java applet or application:

Create a Java Project and include the following class to it:

class test
{
   public static void main(String[] args)
   {
    String build;
    build=com.ms.util.SystemVersionManager.getVMVersion().getProperty
         ("BuildIncrement");
    System.out.println("Using build "+build);
   }
}
