While running updates, after the first series were installed, it complained that it couldn't use IE 6 for updating any longer, and led me to a download page for IE 8, since it said that IE 9 wasn't compatible with XP. So I downloaded and installed IE 8, but afterward checking in it's About info, it still said that it was IE 6, however it still let me continue with Windows Update. During that series of downloads, it also listed IE 8 as an option, so I selected it. That time was successful, because it now identifies itself properly. However when I choose Windows Update from the Control Panel, it now opens Opera, and is blocked by MS. If I simply minimize Opera and click Windows Update again, it will open IE, but is still blocked. This seems quite strange to me, because the window that Updates usually uses for that purpose doesn't look like IE to me, but a window specifically designed for the purpose, kind of like a Windows Explorer windows without the folder tree on the left. Automatic updates still works properly, but that doesn't permit me access to optional updates. How do I get it to work as before?
