Kinda sketchy on the details here.
Can you successfully update via the Start menu (vs Automatic Updates)?
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)?
Has a Norton or McAfee application ever been installed on this machine
(e.g., a free-trial version that came preinstalled when you bought it)?
