Windows 10 Icon back again

Hi everyone;

After trying Windows 10 for about a month or so I decided to go back to Windows 8.1 I'm very glad I did and now I an be happy again. Almost!

I now have that Windows 10 Installation icon in the System Tray again, and in the Windows Update it keeps showing me an update to Windows 10 along with any other Windows updates.

Can someone help me in permanently removing the Windows 10 icon from the System Tray and also tell me how to prevent it from showing up in my normal Windows Updates?

Thank you for any help you can offer here. It would be most appreciated.

Thank you for your time.

Bud
