yes... 2nd tuesday of the month (so next tuesday), but since its only for insiders right now, least few months this 2nd tuesday was more like thursday/friday....
No. I have never had a single problem with any computer. LOL. I've planned to install this 20H1 on all of my machines when the new CU releases. Thanks for the explanations!
IP rings have no specific schedule for CU like @Enthousiast mentioned. By the way, there is no CU for other GA builds as well because this month started from Wednesday last week, so this Tuesday is the first one not the second one. Actually, I was confused that this Tuesday was the second Tuesday of this month. Hopefully, we will see the new CU in next week.
I'd be surprised if they release anything else this week, security updates are going be released next week, that's when we will see the updates.
19041 did never follow the normal update release frequency, it's insider and they can get updates whenever msft decides,
