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

Question

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 CONTEXT: 0x00000005

Command:

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

Error:

This didn't work either :

powershell -Command "$client.Credentials = Get-Credential; $browser.Proxy.Credentials =[System.Net.CredentialCache]::DefaultNetworkCredentials; (New-Object Net.WebClient).DownloadFile('https://some.hostname/file.txt', 'file.txt')"

Answer 1

This worked for me :

powershell -Command "[System.Net.WebRequest]::DefaultWebProxy = [System.Net.WebRequest]::GetSystemWebProxy(); [System.Net.WebRequest]::DefaultWebProxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials; (New-Object Net.WebClient).DownloadFile('https://some.hostname/file.txt', 'file.txt')"
