Windows 10: 2nd Monitor isn't working

Yesterday my 2nd monitor stopped working. It was working fine two days before that. I have tested the monitor with another laptop and it works fine. I uninstalled, reinstalled, and the updated all of the drivers for the display adapters, generic pnp monitors, and the Microsoft updates as well. It didn't fix the problem. I backed up my files and reset my laptop and that didn't fix it. After digging a little bit i discovered an error with the Nvidia High Definition Audio driver.

Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.

 

Cortana isn´t working

When I hit enter, it did something, but there´s still no Cortana, even after restart. So I tried it again, but now it says that it failed, because it´s already installed and it´s working in PC. So it should work, but Cortana still isn´t here.

 

Color Display on 2nd monitor

I am using Windows 10 on a Dell laptop with a 2nd monitor which has been working fine. For some unknown reason I have suddenly lost the full color range on the 2nd monitor. I don't know if I have changed some setting by accident or what. I have tried
resetting the defaults but that didn't change anything on the 2nd monitor. The primary screen on the laptop continues to work fine. Any suggestions what needs to be done to restore the full color range on monitor #2?
