I got into this mess because I need to remove IE9 beta. I have read all the info on using the show installed updates in control panel programs and features, but win7 tells me there are no installed updates. That is a lie, because this machine has tons of installed updates. I'm beginning to think that it may be time to reinstall win7 since I also have been unable to install SP1. The system keeps saying there is some pre-req needed, but when fallowing all the links there is nothing that helps. This is my wife's machine and she is getting real annoyed that every time she starts up ie it tells her that there is a new update available and yet it will not install. There are other issues as well, such as not being able to get the Blackberry Desktop to install because of not being able to install some C++ redistributable. Maybe a repair install will do the trick.
