Windows 10: My computer thinks the windows key is stuck down but it isn't

So, a few months ago randomly my computer would bug and act as if I was holding down the windows key. I thought it was my keyboard at first and it didn't really bother me that much as after a quick restart of my computer the issue was gone. But Today it came back. And it will not go away. It is super strange. The computer allows me to put in my password but as soon as I use the left side of my keyboard From G across to the left it seems to go into this mode of windows key being activated. If I press r windows run comes up. L logs me out etc. I have used the OSK which also has windows key activated and i cant click it to toggle it off and I plug in my other keyboard and it had the same issue. I cant type or use my computer as it just keeps doing windows shortcuts and I cant find any answers or troubleshooting that actually works. I would really like if I could get some help.
My pc specs are:

I5 8600k

1070

16gb of Ram

and the keyboard I use is: Ducky one2 mini my other one is a Razer Blackwidow chorma

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.

 

Computer Won't Reboot - AMD Data Change...Updata New Data to DMI

If he is getting stuck at verifying DMI pool data, that means his BIOS isn't finishing the POST process before it's hanging up. Although I'm confused now because he said he tried re-installing windows which would indicate that the machine is getting through the entire POST process.

I'm confused now. I think we need a better, more descriptive version of what exactly is happening.

Maybe a full step by step process of what is happening?

 

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.
