That only turns off user access to it. It is still used by Windows Update and other internal functions.Windows 7 is not XP. Indeed, in the XP days it was not possible to remove Windows Explorer without rendering the system very unstable. In Windows 7 it is very simple to remove IE:
Control Panel -> Programs and Features -> Turn Windows features on or off -> uncheck Internet Explorer -> OK, apply, maybe reboot.
Now, this of course removes icons and links, but does it remove the actual code? I don't think so. There are several Windows features that use Internet access and I bet they simply use the IE code without "running the IE itself" if that makes any sense. What I mean by that is you don't get an IE window and don't have a corresponding process in Task Manager.
However, what I don't know is whether Windows Update will want you to update to IE9 even if you "turn off" the IE by the above method. Logically thinking it should not (why update the removed program?) but at the same time the vulnerabilities in the other network-aware code should be patched somehow. I am not sure how separated these things actually are.
But at least, if you turn off the IE, you don't need to worry about using it. At the same time, you can have it installed and still not use it. Is there any advantage of uninstalling IE vs simply ignoring it? I don't know any, unless a few MB of space are crucial for you.
