Windows 10: I have a blue circle following my login info and my search bar. It is not going around its...

I have sent a photo of what's happening. It does go away, but comes back anytime I try to enter anything in a search bar. Name, Google search, and password. I've never seen this before. What do I need to do and what is. Why is it on my laptop?

flashing blue circle


Following Windows updates 10/03/2016 and subsequent restart, I had a blue circle constantly flashing next to the mouse pointer as if the system was waiting for a task to complete. I checked various forums for a solution and tried some of the suggested remedies - none of them worked. Today, 12/03/2016, I decided to login to Skype. Lo-and-behold, the constant blue circle has gone away! Don't know why although I suspect perhaps a hung, stopped or suspended process was restarted with Skype.

 

blue screen with spinning circle following reinstall of Win 10

Following a reset of my Toshiba Satellite laptop due to account login errors and then successful upgrade to Win 10 (laptop came with Win 8), I am now stuck with the blue screen/spinning circle. When I turn the laptop on, the sequence of screens I get are:
the Toshiba screen, black screen with spinning circle, lock screen. I can move the mouse, but if I click it to advance to log in, I get the blue screen with spinning circle. Turn the laptop off/on and I repeat the sequence getting stuck at the blue screen
again.

Suggestions?

thanks
