If you'd like to hide the spinning blue circle next to the mouse pointer in Windows, here's how you can do that.
Open the Start menu.
Type "main.cpl".
Click on the first option.
In the window that appears, switch to the "Pointers" tab.
Select "Working In Background".
Click "Browse...".
In the pop-up window, select "aero_arrow".
Click "Open".
When the second window closes, click "Apply" in the first window.
Click "OK" in the first window.
I recommend that you check what processes are running to cause the spinning blue circle. You can do this by doing the following:
Press Ctrl + Shift + Esc on your keyboard to open Task Manager.
Look through the processes and see what's using the most resources. If you spot something unusual, research its name to find out what it might be. From here, you can right-click the process to open its location in File Explorer, or you can end the task altogether. Note that ending the task does not prevent it from relaunching.
Done! You should no longer see a spinning blue circle next to the Windows cursor when a background process is running.
