Ссылка, которую опубликовал Ривз, привела к созданию файла .ps1 с этим скриптом внутри. При запуске этого нового файла в Windows Power Shell открылся проводник, указывающий на фоновое изображение. Мне пришлось изменить ExecutionPolicy чтобы PS запускал файлы .ps1.
Однако каждый раз открывать PS, а затем запускать команду, доставляло больше хлопот, чем я хотел, поэтому я прочитал этот пост и сделал ярлык на своем рабочем столе с целью
powershell.exe -command "& 'C:\A path to the new ps1 file\MyScript.ps1'"
Вот копия сценария, использованного в случае .ps1, по которой ссылка отключается:
