Microsoft should change their way of setting up Windows.
My system normally runs in ramdisk but when I want to install software I boot in filedisk mode so changes are written to the image.
Before I install stuff I first make a backup of my xp.vhd.
Image files are so much better than stupid system partitions.
It's much more convenient to copy a single file than a whole folder structure, and the copy speed is better too.
Microsoft could set up a similar config as the new standard but they won't.
M$ won't change the way they do things because they are afraid to confuse users and they just don't care that much about security.
They just want return on investment and making their OS more secure does not fit the bill in their perspective.
They will only change their security model when forced and there is no pressure at the moment so things will stay the same.
Consumers have become used to antivirus and disinfecting their systems and there is a whole industry that floats on the current blacklisting paradigm so no one really wants to change their ways.
