How to Fix MS Apps Not Starting on Windows

If you're encountering issues with Microsoft apps like the calculator not starting on your Windows system, you're not alone. One common cause of this problem is when the Windows firewall is disabled and greyed out. Fortunately, you can resolve this issue by following these steps:

1. Open an Administrative Command Prompt: Right-click on the Start menu and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)." This will open a command prompt window with administrative privileges.
2. Run the Registry Command: In the administrative command prompt window, enter the following command:

   reg add "HKLM\SYSTEM\CurrentControlSet\Services\mpssvc" /v start /t REG_DWORD /d 0x2 /f

   This command modifies a registry key related to the Windows Firewall service to set its startup type to automatic.
3. Reboot Your Computer: After running the command, restart your computer to apply the changes.
4. Verify MS Store Apps: Once your computer has restarted, check if the Microsoft Store apps, including the calculator, now start properly.

Following these steps should restore functionality to your Microsoft Store apps on Windows. If you continue to experience issues, further troubleshooting may be necessary.
