Windows 10: Can someone please help me find out why my bluetooth just isn't working now?

So last night I was playing a game with my mate and suddenly bluetooth just stops working, the devices didn't turn off or anything, just a random disconnection, anyway so I said I'll restart my computer, and when I do, bluetooth isn't showing up on my quick menu or actually able to connect through settings. It doesn't show up in device manager without showing hidden properties. I don't know what to 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.
