I very recently purchased a new laptop, as my previous one "crashed and burned". As part of the deal, with this new unit, I'm burdened with the less-that-stellar Windows 10 program. I'm finding that on one particular automotive chat site, one that I've frequented for a long time (about 16 years, and 50,000 posts), I now randomly get the error message that it's security certificate has expired. It's annoying, but I haven't had it happen here, at least not yet.
