When TV first connects my desktop computer to my remote desktop computer, I used to log-on by clicking on a Ctl/Alt/Delete button at the top of the screen of my remote computer.. Now, that button has disappeared and I can't get logged on. I may have changed a setting inadvertantly on my remote desktop computer. Any way to get that Ctl/Alt/Delete button back? I'm locked out of my remote desktop! I use Windows 10 on both computers.
