I see a very long list of complaints spanning more than a year that: 1) the fingerprint scanner issue persists in Win 11, and 2) your directions do not solve the problem. I know, you cannot solve it. Only Microsoft can. And Microsoft is ignoring everyone.
I am on my second computer in the span of time this thread has been live, and I have had intermittent issues with the fingerprint scanner upon boot.
Furthermore, three friends are having the same issues. I do not know others, ONLY because I have not asked.
It appears the fingerprint reader works about 50% of the time for me upon boot up. It works nearly 100% of the time after successful login without me taking any action.
During the time I have been experiencing the problem, I have been running Win 11 Pro on Dell. One friend is running Win 11 Home on Dell. One is Win 11 Home on Hp. Another Win 11 Pro on Asus.
I'm hazarding a guess there is a delay issue during boot that Microsoft needs to address. I've been experimenting and haven't found the right setting yet.
