I want to try to check to see if my Windows Update on my Windows 8 PC is up-to-date, but both: https://www.update.microsoft.com/microsoftupdate and https://windowsupdate.microsoft.com Tell me its an untrusted connection with this message: This Connection is Untrusted You have asked Firefox to connect securely to www.update.microsoft.com, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. What Should I Do? If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue. I've noticed that most sites 99% don't have trusted certificates.. I would like to know if there is a way I can update my certificates.. I'm not sure if this belongs in the security form or here but I bet someone knows here.
