Wow.
Again, we don't know the history of your machine. On an unaltered system, disabling/enabling the charms bar should work as normal. You say you have searched online for different ways to accomplish this and nothing has worked. What other things are you expecting us to tell you do. We are telling you that something is up with your operating system. When was the last time windows was reinstalled on this pc? If never, you are way way over due. Reinstallation of windows should happen every couple years at a minimum. My install is 3 years old now and it needs a reinstall because of it slowing down, I even have an nvme SSD as boot drive.
Your choices right now, are backing up your data and reinstall windows 8 or upgrade to windows 10 using this website.
Download the tool and follow the prompts to update your pc to the latest version of windows 10.
Or do nothing and live with the way it is.
By the way, have you downloaded and ran ccleaner to clean your system of old unneeded files and to make your system faster? What about using Malwarebytes to scan your system for malware?
We aren't here to get you upset or anything. There just isn't a magical way of fixing things if you exhausted all other options of trying to do what you want to do. Then end problem is that something is wrong with your OS. And there is only 1 way to fix that.
