A few nights ago I upgraded my Windows 7 PC to Windows 8. This morning, when I logged into my PC, I noticed the little flag in the system tray, in desktop mode, had a red "X" on it.

I checked it and one of the issues was my needing to tell Windows 8 that I trusted my PC. I clicked on the link to trust my PC, and saw the button to tell it to trust my PC, and so I did.

After doing that it send it had sent out an email to a really old email address I had, which hasn't been valid for many years.

Now what? Will that "trusting my PC" be invalid, because I can't respond to it (which certainly isn't true, if it's sending messages to so old email address). I didn't even know that Windows still had such an old email address.

I'm concerned that I won't have a trust relationship with my own PC, that somehow or other whatever holds onto my information has old information and that I am not sure how to change it in as fast a manner as possible so that I can trust my own PC.

How do I do these things?
