Hi Abdul,
I don't quite understand your thinking. It doesn't sound like you understand the original description.
Parallels for Mac is used to run the Microsoft Windows product. From my perspective, the Parallels icon is in the Mac menu bar, and I can click the icon to (say) enter and exit Coherence view of the Windows product. Likewise, I am asking that when Windows updates are available, that Parallels pass that information along to the Notification system that appears in the Mac menu bar.
I'm not certain why you believe Microsoft would perform engineering work on the Parallels product. I'm of the impresion that this would be a feature that Parallels engineers would need to implement.
Thanks,
Rod
