Или неправильный синтаксис запуска через CMD? »

Пробуйте так:

Код:

set "ps=" & for %%X in (powerShell.exe) do set "ps=%%~$PATH:X"
if not defined ps set "ps=%systemRoot%\system32\windowsPowerShell\v1.0\powerShell.exe"

For /F "UseBackQ delims=" %%a in (`"cmd /c "
  "%ps%" -ExecutionPolicy ByPass -NoProfile -command "./Dell_MetroAPP_and_Other_Win10_3.ps1"
""`) do (
  echo %%a
)
