Windows 10: My audio isn’t working at all with the new windows update?

So my laptop updated to the newest windows and all of the sudden my audio went out after working for a few days?! It says all of my stuff is up to date including my audio drivers? I’ve tried everything I uninstalled it and reset my computer…still doesn’t work. I don’t understand why this is happening I’ve reset my entire computer once already and had to restart everything from the ground up…I really don’t want to do it again because something isn’t working. My computer is a Acer Predator Helios 300.

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.
