Error: Unable to run bash on Windows 10 CMD is an issue that affects users who have installed the Ubuntu app on their Windows 10 machine. This error occurs when the user attempts to right-click and select 'Run As Administrator' within the Ubuntu app or tries to run a bash command from the Windows Command Prompt (CMD). The error message displayed in both cases is 'Error: 0x80070005'.

This error can be frustrating for users who are accustomed to running bash commands from Linux or macOS systems.

⚠️ Common Causes

The primary reason for this error is that the Ubuntu app does not have the necessary permissions to run as an administrator on Windows 10. This is due to a security feature implemented by Microsoft to prevent unauthorized applications from running with elevated privileges. As a result, when you attempt to right-click and select 'Run As Administrator' within the Ubuntu app or try to run bash from CMD, the system denies the request due to a lack of necessary permissions.
Another possible reason for this error is that the Windows Security Software (such as Windows Defender) is blocking the execution of the bash shell. This can occur if the software detects the bash shell as a potential threat and prevents it from running.
