Chrome bypassed a lot of security policies by installing itself in the user profile instead of the normal installation in the Program Files folder, because otherwise it would have never been allowed in many corporate environments.

Microsoft can manipulate Windows to make Chrome look bad, but while this could have been useful fifteen years ago against other less popular software, now Windows has serious competition in the form of smartphones and tablets.

Microsoft can't do anything about Android. And people are using Android instead of Windows to browse the Web more and more every day.
