Windows 10: windows can't activate which is why i suspect my windows media feature pack isn't here

so this happened some weeks ago after i did a pc reset. the leading theory i have is that i messed with something in the uefi settings while booting so bad that it did this. and i have tried trouble shooting looking for corrupted files via cmd reinstalling windows resetting uefi settings to normal. nothing works at all and this hinders me in using the media player as well as playing some games. when i try to trouble shoot my windows activation it just gets interrupted and says i need to get support which is what i have resorted to now. the error code i get while trouble shooting is these two.

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.
