Windows 10: My laptop isn't responding to anything?

My samsung galaxy book has had this issue before where it doesnt respond to any interactions such as the caps lock, charging light, and power button. I've tried to restart it, boot in safe mode, ctrl alt del. When I got it fixed the first time, I was told it was an issue with updating the BIOS, but I don't know how to fix it myself. What do I do?

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.
