Not true for us. We EV cert sign (the more expensive one) and my CEO ( the only one left that uses Windows) had this very problem. Apparently the first time a newly signed binary is run it can take up to 15 minutes for defender to allow it. First time I saw this, it was really annoying and confusing.
Interesting.
I regularly download our signed installer often within a minute of it being made available, never noticed a delay.
Maybe it’s very the first time Windows Defender sees a particular org on a cert.
I renewed our cert literally on Friday, tested by making a new build of our installer and could instantly install it fine.
You sure there was no other non Windows default security software on your bosses machine?
They did change it, I think after some debacle with Nvidia pushing an update. They seem to want devs to submit their files via their portal now to get rid of the screen: https://www.microsoft.com/en-us/wdsi/filesubmission
I've never submitted our installers to there (or anywhere). I'm often the very first to install new builds (particularly our nightlies) and never had a delay or anything.
Did you install it on the same machine or a different one?
I was always able to install immediately on the same machine.
