I do not have updates if IE8 is available, whether it's naked or with patches, 100% download svchost.exe. The most interesting, when a clean Windows install IE6 gives an error when accessing the MU. It is necessary that it would work to install IE8, and then delete it, only so MU starts working on IE6. If all this is done, upgrade to MU within 1-2 minutes.
I noticed while two components that violate the search for updates, it's IE8 and SP3 for the installation of the compatibility with 2007 Office, which is put for the 2003 version.
