Windows 10: Is there a way to fix the dash key that isn't working?

All my other keys work on my keyboard but my dash key so I bought a new keyboard thinking that it was the problem but when I plugged up the new keyboard the dash key still isn't working.

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.

 

Messaging Ringtones on T-mobile Dash

I just got my T-Mobile Dash and love it. But I was wondering is there a way to use my own ringtones for incomming text messages? The Ringtones I downloaded to the phone will show in the list for Ringtones but not in the list for Ringtones for Text Messages.
Anyway to get them in there so I can hear my Ringtones when I get a text message?

Thanks in advance!
