In a previous blog post I had talked about how curl in Powershell was an alias for the Invoke-WebRequest cmdlet.

This was a well intentioned move, leveraging the muscle memory of experienced users.

The problem is that curl the tool is a very comprehensive tool, and an immediate problem that people with Linux experience ran into was that invoke-webrequest does not recognize the bewildering array of parameters and sub-commands that curl supports.

This led to a situation where scripts would surprise users, especially experienced users.

Microsoft made a change from Windows build 1804, where they made the following changes in PowerShell

  1. Removed the curl alias
  2. Packaged with Windows the native curl executable

You can verify this if you are running a recent build by running the following command in your console:

curl --version

You should get back a response like this:

curl 7.79.1 (Windows) libcurl/7.79.1 Schannel
Release-Date: 2021-09-22
Protocols: dict file ftp ftps http https imap imaps pop3 pop3s smtp smtps telnet tftp
Features: AsynchDNS HSTS IPv6 Kerberos Largefile NTLM SPNEGO SSL SSPI UnixSockets

You can even check where it is installed:

where.exe curl.exe

You should get back a result like this:


You can now comfortably use curl in your Powershell scripts with the full features it supports, or if you wish, directly use invoke-webrequest.

This change was made to both Powershell and Powershell Core.

Happy hacking!
