Windows 10: Small, black and white circles next to desktop icons. What do they mean?

I opened my computer this morning and found nearly all my desktop application icons had this symbol next to them. In about 20 minutes they disappeared as my desktop refreshed the icons.

What do they mean?

Network Icon with white circle

Hey guys,

So I locked my PC today and noticed that on the lock screen the network icon had a small white circle on the lower right hand side of it. Basically it was exactly where the red x shows up if you aren’t connected.

I hovered my mouse over it but nothing showed up and when I went to log in the circle disappeared and the normal network icon was showing.

Does anyone know what this white circle means? I can’t find anything online about it.

I know the wifi symbol can show a white circle to the upper right but everything addressing it online yields any actual results as to what it means.

 

Windows 10 Desktop Icons Change Periodically

Periodically, my Windows 10 desktop shortcuts change appearance; a small "green circle" with a "white" check mark is displayed in the "bottom center" of the desktop icon.

I have two questions: (1) why do the desktop icons change and (2) what the green circle with the "white check" mean?

 

I have an "icon" that appeared on the desktop, it is a small white square with a red circle with a red line going through it

under that is a gray box that says Cloudy 45 degrees shows hi and low and Washington as the location

Right click on it and nothing happens. Cannot drag it anywhere. Cannot delete it.

How do I get rid of it as it is in the middle of my screen?
