Windows 10: Can't login to computer. PIN isn't working.

A few months ago my Microsoft account was compromised. They changed my email and password so I lost access to that account. I contacted support and they told me that they couldn't give my account back and instead would permanently suspend that account. Everything was fine until yesterday.Yesterday I tried signing onto my computer with my pin and it says:"Your credentials could not be verified""Something went wrong and your PIN isn't available status: 0xc000006d, substatus: 0x0. Click to set up your PIN again"When I try to reset my pin, it tells me that it'll send a code to the email I don't

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.
