About 10-20% of the time when I turn on this system, the lock screen will just display nothing. I have Win10 Pro ver 2004. I remembered once that pressing CTRL-ALT-DEL brings up the logon screen, which it does. However, I also use Winaero Tweaker, with which I disabled CTRL-ALT-DEL at logon. What else can I do to keep this option disabled? Thanks.
