microsoft windows update fails

Clarifications

You wouldn't call the Operator to make an inquiry, now would you? ;)

Some of them prevent you from visiting the update web site.

Use your anti-virus/anti-malware scanner while booted in Safe Mode and make sure your system is absolutely clean. If it is, reboot and try another web site such as www.microsoft.com. If you can visit that site, try the update web site again.

By the way, just how are you going about trying to access the update web site?

And, most importantly, what operating system and version are you running?
