Some or all of my Metro style apps fail to run.

1. Check to make sure that your screen resolution is at least 1024X768
2. Confirm if the issue reproduces with all user accounts. Metro apps aren’t supported if you are running with a built-in administrator account (happens mostly when upgrading).
3. Check if UAC (User Account Control) is enabled. UAC must be enabled for Metro apps to work. To check, simply type UAC from the home screen and it will appear on the Settings search result.
4. Try running System File Checker to see if it can identify/restore any system files. (See instructions below)
5. Refresh your PC. (See instructions below)

If you get to step 4, you will need to open an elevated Command Prompt. This can be done by:

• Enter the Start screen
• Press Windows key + C on your keyboard to show the Charms bar. (If you are using a touchscreen: touch the right edge of the screen and swipe your finger toward the center of the screen to show the Charms bar)
• Click Search
• Type Command Prompt into the Search field
• Right click Command Prompt (If you are using a touchscreen: Touch and hold your finger to the Command Prompt, slide your finger down until you see an outline around the tile, and finally release your finger from the screen.)
• Click Run as administrator
• Enter the command: sfc /scannow
  Note: If you are using a touchscreen you can open the touch keyboard for the Command Prompt by tapping the keyboard icon displayed on your Taskbar near the System tray.

Once the scan has finished the results will be displayed within the Command Prompt. Try accessing the Metro style apps that weren't working before. If they don't work, try restarting your computer and test again. If the apps still don't work properly the next step will be step 5.

If you get to step 5, here is what will happen when you refresh your PC:

• Your files and personalization settings won't change.
• Your PC settings will be changed back to their defaults.
• Apps from Windows Store will be kept.
• Apps you installed from discs or websites will be removed.
• A list of removed apps will be saved on your desktop.

To refresh your PC:

• Press the Windows key + C on your keyboard to show the Charms bar (If you are using a touchscreen: Touch the right edge of the screen and swipe your finger toward the center of the screen to show the Charms bar.)
• Click Settings
• Click More PC settings
• Click General in the left column
• Under Refresh your PC without affecting your files, click Get started

Then follow the instructions provided on the screen to complete the refresh process.
