You may have a problem opening metro apps like Edge, Calculator, or Calendar in Microsoft Windows 10. A message that says “This app can’t open. (App name) can’t open while User Account Control is turned off.”
A similar error message that may appear is “This app can’t be activated when UAC is disabled.”
You can solve this problem with these steps:
- Select the “Turn on User Account Control” link on the message that appears, or go to “Control Panel” > “System and Security” > “Security and Maintenance” > “Change User Account Control settings“.
- Slide the slider to any of the top 3 selections.
- Restart your computer.
FAQ
Why do I have this problem repeatedly even after I change the UAC setting?
The UAC setting may revert because of a Group Policy that is enabled on your computer. If you are in an enterprise environment, contact your IT department or System Admin.
Is there any way to run Metro apps with UAC disabled?
Nope.
