I don't know why if I replace old, system builtin powershell executable
with powershell 7, scripts fail with this error:
The argument 'Set-Item -Path ...' is not recognized as the name of a
script file. Check the spelling of the name, or if a path was included,
verify that the path is correct and try again.
Adding -Command at the end of flags just fixed it.
