Safe, but is it legal?
All of the security upgrades that Microsoft has been focused on is probably a good thing for most users, but is a double-edged sword for Microsoft themselves as The Economist points out. Certainly Microsoft is allowed to fix security bugs but sometimes when more sophisticated functionality is requrired to plug security gaps, they start stepping on the toes of their various consent decrees. It is going to be interesting to see how they can play adding antivirus, firewalls and digital security to Windows over the next few years from both a technical and legal viewpoint.
