Very true! There should be no need for you to do so. Its good that real-mode DOS support was removed because it drastically reduces device driver loading time, boot-time, improves performance, and reduces attack surface for viruses.And as for SR - indeed! It needs to be updated with WindowsUpdate to work. But then, no one EVER likes it. It eats your HD space and then when you're desperate for it, it doesn't quite restore your system to perfection. Disable the darn thing, lol.
