Windows 10: Windows "PIN isn't available"

i changed my RAM and now windows when booting up says "Your PIN isn't available. Click to set up your PIN again."I can't do this as PIN set up requires verification from an old email account that I dont have. Changing the security email takes 30 days to do.How can I get around this? I am locked out of my PC now.

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.
