Windows 10: No cursor (arrow) on my PC after powering up.

I have windows 10 on my PC and when I power up (start) my PC for the day I do not have a cursor (arrow, pointer) to sign on. I have to manually hit the power button until my PC goes off, then I power up again and there it is my cursor arrow and then it is OK. How can I just power up and not have to shut down my PC just to sign on?

The cursor changes the shape from the arrow to a circle with an up arrow and an arrow down

When I have opened a program like Edge on my Windows 10 PC, the cursor changes form from an arrow to a circle with an up arrow and an arrow down.
This new symbol can not activate anything by moving it around with the mouse.
To close the open program, press Ctrl + Alt + Del to get to the job list.
At the same time, the circle symbol turns into the well-known arrow, and I can continue the work normally.

How do I avoid the annoying circle icon?

Back arrow

In Internet Explorer, when my cursor hovered over the "Back" arrow, a list of recent pages would drop down. I can't make this happen with Edge. Any suggestions?

How do I make my arrow cursor a little bigger?
