One of our biggest annoyances about using Windows 8 on a desktop PC was the Hot Corner feature, which brought up the Charms Bar when you hovered your mouse in the top right hand corner of the screen. The Charms Hot Corner is now optional in Windows 8.1 and here is how to disable it.
If you are using Windows 8, you can use a registry hack to disable the hot corners.
How to Disable The Charms Hot Corner Without a Registry Hack on Windows 8.1
The setting falls under the Taskbar and Navigation properties, so right click anywhere on the Taskbar and choose Properties from the context menu.
Then switch over to the navigation tab.
Here you will need to uncheck the “When i point to the upper-right corner, show the charms” box.
Click apply and you are done. Of course, you can still pull up the charms bar by using the Win + C keyboard combination.
That’s all there is to it.
