It depends on how one defines "installation". If it's hardcoded into Windows 7 SP1 that's one thing. But if it came with the OP's "Installation" from the company that manufactured the PC, that's another. When Windows 7 first came out a friend of mine was telling me about the new "Dock". Since I never saw that I had to look it up to discover it's really the "Dell Dock", added by Dell, which had no connection to Windows or Microsoft except as an added application.
As far as SP1 is concerned, I added that to my original Windows 7 and it did not upgrade my version of IE. In my case IE9 only appeared as an optional update on Windows Update, and can be easily hidden. But it's easy to install it thinking it's required since Microsoft may call it "important".
