Addendum: I clicked the X to get rid of the Security Warning box, and what happened next was that I got the following message at the Microsoft Update site: “Install the ActiveX control required to view the website. The website will not display correctly on your computer without this control”–followed

In the “Windows Update”, there has a link to get other microsoft product update, when i click the link, it will turn to “Microsoft Update” website, after i accept to install the activeX, it take me to the error page and the error code is “0×80070002″, but i still can update the windows by “windows

0×80070570 – ERROR_FILE_CORRUPT If relating to the WU or MU Page, recommend re-installing the ActiveX controls If relating to the HotFix – then re-download the fix manually

I tried download center and it let me download IE8 beta 2. Installed it and everything is working normally just like before. Windows update is no pain anymore. Thanks …
