Oracle Java 8 version does not turn os.name property into Windows 7 when run in the compatibility mode

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run this code on Windows 10, running in compatibility mode
public class OSN {
  public static void main(String args[]) {
    System.out.println(System.getProperty("os.name"));
  }
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Windows 7
ACTUAL -
Windows 10

REPRODUCIBILITY :
This bug can be reproduced always.
