I've recently got Win 8.1 Pro and a new keyboard and mouse(Slimstar c110). The keyboard worked but suddenly both of my Ctrl keys aren't working.
I tried doing tests and doing shortcuts but they aren't working, I'm almost 100% sure the keys themselves aren't broken.
Are there any options that could have disabled my Ctrl keys?

I had the same problem for months, both Ctrl keys and back arrow key did not work.
I had to reinstall Google Chrome, all keys then started working again.
This was possibly by accident or a related Chrome issue.
