Windows 10: Unusual activity security query - I selected the wrong answer and can't change it in the app

Somebody has been trying to crack my password and I accidentally selected that a login from the USA was me. I have changed my password, but can't find any other way of changing my selection, so the USA login has been marked as successful.Please advise.

Definition of "Unusual Activity Detected"

Hello,

I recently received an email notification that "Unusual sign-in activity was detected."

I reviewed the Recent activity page and under the column labeled "Session Type"> "Sesson activity" it was listed with "Unusual activity detected"

Does this mean that they were successful in signing into my account or were they blocked by a security code or question?

I know there is another question posted with this same subject title, however, they did not get a helpful answer, so I am reposting.

Thanks for the assistance!

 

Microsoft account unusual sign-in activity

Thank you for the reply. I have answered your questions in bold.

But I still fail to see why any of the questions/measures apply to my situation when Microsoft's "Review recent activity" log shows no "unusual sign-in activity" whatsoever. There are approximately 20 sessions showing on my activity log currently, and everyone
single one of them shows them to be: my computer, my IP address, my location, my operating system, my browser; all at times of the day when I was on my computer...

So unless Microsoft's "Review recent activity" page is inaccurate, where on earth is the "unusual sign-in activity" and why am I getting daily emails alerting me to something, that according to Microsoft's "recent activity" log, does not exist?

Thanks for your continued help/efforts,

SR

03/03/17: Update: and, FTR, I got the email again last night, 8 days in a row now. And once again, there is no "unusual sign-in activity" showing in my "recent activity" whatsoever.
