Windows 10: Keyboard isn't functioning well. PLEASE HELP !!!

Out of the blue, my keyboard stopped functioning well. Now, I have to click the function key and the letter a to get "a" otherwise i will get "`a". Same goes for the letters k, f. "d" will type "d" and lower my brightness at the same time, 6j, -;, and Enter keys will not work properly even with the function key. Shift + F will result in %F, Shift + A will result in ~A, Shift + S is reloading my webpage which is odd etc. \A lot of the keys are messed up.I tried updating my driver, running keyboard troubleshooting, pressing Fn + Caps lock, Fn+ f12, Fn + Shift + Numlock, Fn + Numlock nothing work

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.

 

Intermittent keyboard non-functioning


I use a wireless mouse and keyboard. Every now and then, often enough to be irritating, the keyboard fails to function: the mouse works properly. The keyboard problem persists for a few minutes, after which it works again. There is no discernable pattern to this problem.

This is the third wireless keyboard to show the same problem, suggesting something is wrong elsewhere.

The keyboard batteries are not responsible for the failure.

On the same desk is a cordless telephone.

Any helpful suggestions would be very gratefully received.

 

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.
