Sorry, no way I'm relying on a Band 2 for that.
They would have to correct the issue of huge HR spikes before a warning would have any real value. If this existed today I would be getting constant warnings.
Not that I expect articles to be all roses and lollipops, but so many of these "is W10 doomed?" articles could become self-fulfilling prophecies. People read them and then either avoid Windows...
Now, I admit, I don't use my W10 laptop that much, but I don't think that I have rebooted it once, to fix an issue, since I left the preview.
Then, why are you here?
