Windows 10: Recently changed hardware and my retail windows key isn't working

Changed my mobo and cpu, but I can't activate windows. I have a retail key, but I keep getting errors not matter what (reactivating, troubleshooting, change key). Any help is greatly appreciated.

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.

 

Windows 8 Pro Retail => Windows 10 Pro (Free upgrade) Fails Activation after hardware change

Hi,

I bought 2 retail licenses (one for my desktop and one for my laptop) for Windows 8 several years ago and upgraded to Windows 10 (via the free upgrade). Recently I had to change some hardware (motherboard) and I get the following error code when trying to
activate Windows: 0xC004C003.

I have tried the following, all of which have failed.

1. Troubeshoot -> I recently changed hardware on this device (I can only see my Laptop License and not my desktop)
2. Provided the Installation ID (via phone helpdesk) on two occasions.

First help desk technician suggested I buy a new Windows License and the second suggested I reinstall and use Windows 8. Both suggestions from help desk are ridiculous.

How do I proceed without having to:

1. Pay for a license I should technically already have
2. Downgrade back to Windows 8 (loose time / data)
