I think I figured out how to fix the WORD shortcuts CTRL+C and CTRL+V so they work again.
My Word CTRL+C and CTRL+V suddenly stopped working after they were working just fine.
I finally discovered that the reason they no longer worked was because the shortcuts for COPY and PASTE on my word were suddenly changed (have no idea why) to CTRL+INSERT for COPY and SHIFT+INSERT for PASTE.
Here's where I found the shortcuts and how i changed them:
Go to Word -->OPTIONS --> CUSTOMIZE RIBBON --> at the bottom the screen find "Keyboard shortcuts" and click on the "Customize" button -->
Under category choose "Home Tab"
Under Commands choose " EditCut"
Check what is showing in the window that says "Current Keys". If it says anything other than CTRL +C or nothing at all that must be the reason why CTRL +C is not working for you!
update by standing in the window under "Press New Shortcut Key" and holding CTRL+C as you normally would copy.
Click on "assign" at the bottom of the screen. The shortcut will be added to "Current Keys".
At this point you may also want to remove the silly shortcut you had there before (in my case CTRL+INSERT).
Do the same for Command EditPaste.
while you're at it, you may want to change some other wierd shortcuts you may find... ;-).
when done click on close --> OK
and give it a try. it worked for me :-).
