This new case of Windows has no access to the user’s normal operating environment, which means that it has no access to local storage, any domain credentials, installed applications, memory etc. To put it simply, the employee of a corporation will be accessing the particular website in a vacuum through which an attacker will not be able to gain access to the local system or any other system in the corporate network.
