Sometimes we get a pop-up on Windows stating that sign-in is required for some accounts. It is annoying because this pop-up keeps showing after fifteen minutes or so if I canceled it.
In my case, I was receiving this pop-up for some problem in my work or school account. Whenever I checked my work or school account under manage my accounts, I found no warning or message that would indicate the necessity to sign in again. Everything looked normal. It created confusion. For once, I suspected my system was infected by some virus and was afraid to sign in from the sign-in option on the pop-up. The account belongs to an institution, so I had to be cautious.
Later on, I was able to find out that the issue was indeed a sign-in issue. And I was able to get rid of that annoying pop-up. In this video, I have shown the steps that I followed as a solution. It is just a simple sign-in process from the "Manage your account" option.
I have not received that sign-in required pop-up again. I hope this video proves to be useful to you. Thank you.
