Windows 10: How to add or remove icons from the "show hidden icons"

right now i only see ccleaner and nvidia icon on my hidden icons in the taskbar and i cant find where to add or remove icons from there.

under task manager/startup i see ccleaner there but no other programs.
right now i only want to add avira antivirus to my hidden icons and i have checked the settings in avira but there is no option there that will make the icon visable under hidden icons.

when i reinstalled windows a couple of months ago the icon was there but not anymore. when i start avira and close it again it will show up and remain as a hidden icon but after restarting my computer its gone again.

so how do i fix this?

Removing desktop icons

the icons are located in 'all users' folder somewhere (for example, i see a few shared icons in "C:\Users\Public\Desktop" )

The only way to fix those, is to remove the icons from there, and place them on to each users desktops manually. an admin may need to do this.

 

Removing desktop icons

I want to remove some Icons from my desktop, but Vista asks for Admin permission to continue (I'm not an admin *Frown ).
It seems that whenever I delete one of these icons from my desktop, it is also removed from all the other user accounts. For example, I deleted the Skype icon from my desktop, and it was then removed from everyone elses as well.
How can I delete icons from my desktop only, without affecting anyone elses?
