How do I reset Windows Update components?
http://support.microsoft.com/default.aspx/kb/971058
What anti-virus application or security suite is installed and is your
subscription current? What anti-spyware applications (other than Defender)?
What third-party firewall (if any)? Were any of these applications running
in the background when you installed SP2?
Has a(another) Norton or McAfee application ever been installed on this
machine (e.g., a free-trial version that came preinstalled when you bought
it)?
Free unlimited installation and compatibility support is available for
Windows Vista, but only for Service Pack 2 (SP2). This support for Windows
Vista Service Pack 2 (SP2) is valid until November 26, 2009. Availability of
chat or e-mail support differs depending on your geographic location. Go to
http://support.microsoft.com/oas/def...4&gprid=582034 &
select appropriate category (i.e., Download issue; Installation issue;
**Issues after you install a service pack**).
