Tried running bash by renaming it to bash.exe using both CMD and Powershell and both return "Access denied.
Even though Windows 10 already has Terminal and I was getting
[error 2147942405 (0x80070005) when launching `C:\bin\bash -l']
I downloaded Terminal Preview which still throws the same error. Is Terminal or Terminal Preview the only way to run bash? There might be a way to configure cmder to use bash in a similar way you suggested for Terminal. Don't know how yet.
