No modern or connected environment should utilize it; complete migration to standard Java environments is the only viable long-term solution.

At the time, Java’s "Write Once, Run Anywhere" (WORA) philosophy—championed by Sun Microsystems—was gaining massive traction. Microsoft’s version was often praised for its performance and speed, making it the most popular JVM for Internet Explorer during that period. Key Features and "Embrace and Extend"
