I saw this error code this past weekend when I was working on my parents’ new laptop, which runs Windows Vista Home (I think that’s the version). It took me a while to figure out, but all it meant was that there was an issue trying to get an update. The reason: the computer’s date had been set 4 years into the past. Once I went and corrected the date, Vista was able to update correctly. Take that, Code 80072F8F!
After testing this on my work computer, I found that this also that the McAfee AutoUpdate will fail to update as well if the computer’s date is in the past as well. So, if you see that error message in Vista, or have issues with antivirus and other programs failing to update, check the date.
