This didn't work either :

How do I download a file using windows command line without having to input a proxy password?

After looking at various stackoverflow questions, I found several ways to download a file from a command line without interaction from the user.

The only one that worked for me also works only on Windows 10 natively :

curl -sko %TEMP%\file.txt "https://some.hostname/file.txt"

But installing an external tool like wget/curl is what I want to avoid.

What didn't work for me because of proxy errors :

Command:

bitsadmin.exe /transfer "dljob" "https://some.hostname/file.txt" %TEMP%\file.txt

Error:

DISPLAY: 'dljob' TYPE: DOWNLOAD STATE: ERROR
PRIORITY: NORMAL FILES: 0 / 1 BYTES: 0 / UNKNOWN
Unable to complete transfer.
ERROR FILE:    https://some.hostname/file.txt -> E:\Users\xxx\AppData\Local\Temp\file.txt
ERROR CODE:    0x80190197
ERROR CONTEXT: 0x00000005

Command:

powershell -Command "(New-Object Net.WebClient).DownloadFile('https://some.hostname/file.txt', '%TEMP%\file.txt')"

Error:

Exception calling "DownloadFile" with "2" argument(s): "The remote server returned an error: (407) Proxy Authentication Required."
