Windows 10: Why can't I lock my lost device and why isn't its location updating?

I lost my laptop, but when I go into find my device in the microsoft page, the last time its location was updated was 12 hours ago, when I had my laptop, and has not updated since. Any attempts to lock my device have failed too, as I keep getting a message that says 'failed to lock the device but we will email you when we successfully do so'. I have not gotten an email for 12 hours despite multiple attempts to lock my computer.

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.
