Right click on the “Eye-One Display 3 (Argyll)” or “ColorMunki Display (Argyll)” device driver in Control Panel > Device Manager and select “Uninstall” to remove the existing driver. If it appears, check the box to "Deleted the driver software for this device".
You'll then need to uninstall the Argyll (i.e., DisplayCal) program and the reboot the computer
Delete any Display Cal and/or Argyll directories left behind (C:\Program Files (x86) and/or C:\ProgramData) and then reboot the computer
