Does Microsoft have the powere to make their Windows OS be invulnerable like the Mac OS?

I want to know if Microsoft has the power to do such a thing where they can make their OS invulnerable but at the same time compatible with the softwares that are used. Is this possible? If then maybe we can all make suggestions to Microsoft, although we would be copying Mac, it would get Microsoft lots of attention because as I have learned 90% of peoople use the Windows OS because of its ease of use and because it doesnt have software compatibility problems like Mac. But is this possible? If anyone from Microsoft sees this please think about it. It will be a breakthrough in History of OS's
