Disable Windows 8 Hot Corners from Displaying Charms Bar and Switcher

Windows 8 has ‘hot corners’ that allow you to display the Charms bar and Switcher by hovering the mouse in corners of the screen. It can be annoying while working in the desktop.

Windows 8 has “hot corners’ that allow you to bring up the Charms bar and App Switcher by hovering the mouse in the right or left corners of the screen. If you’d rather stay in the desktop environment as much as possible, you might want to disable this feature.

Charms and App Switcher

Tweak Windows 8 Registry

Note: This requires a tweak in the Registry. Before making any changed, be sure to Back it Up first!

First use the keyboard shortcut WinKey + R to bring up the Run dialog, type: regedit and click OK or hit Enter.


Now navigate to the following path:


Right-click the ImmersiveShell folder and select New >> Key.

New Key

Then type: EdgeUI for the new key name. Right-click and select New >> DWORD (32-bit) Value.


Name it: DisableCharmsHint and change the value from 0 to 1 and click OK. This will disable the Charms bar from displaying when hovering the mouse in the lower or upper right corner of the screen.

DisableCharmsHint Value

Then create another new DWORD (32-bit) Value and name it: DisableTLCorner and change the value from 0 to 1 and click OK. This disables the App Switcher bar from displaying when hovering the mouse in the top left corner.


Restart your system and log back in. Now you’ll notice that the Charms and App Switcher don’t come up as easily. You’ll still be able to pull up the App Switcher by hovering in the lower left corner. The touch gestures will still work as well.

Start Tile

Tip: Even though this disables pulling up Charms and Switcher from the “hot corners,” you can still use the keyboard shortcut WinKey + C to bring up the Charms bar or WinKey + Tab for the Switcher.  You can also put the pointer in a corner and slide it up or down to display it.

If you’re uncomfortable making changes to the Registry, you can install Classic Shell, the free Open Source Start menu replacement program. Just go into Settings, select the Windows 8 Settings tab, then click All under Disable Active Corners.

    IObit came out with an app (StartMenu8) that puts the old Win 7 “Start” button on the desktop mode for Win 8 . In addition, it lets you bypass Win 8 Metro entirely and start up to desktop AND disables hot corners and/or sidebar if you choose…without manually changing/adding to bios. The kicker? It’s a free app! Although I personally like tweaking with bios, I’ve only gotten good by sometimes making computers NOT work by doing so :-)

      Huh? Is there a BIOS fix to disable metro? I’m not sure I understand how that would even make sense.
