One of the most frequent asks we hear across the entire Windows command-line spectrum is "I need curl" and/or "I need tar".
If you're one of these people - HAPPY NEW YEAR! 
Windows 10 Insider build 17063 and later now include the real-deal curl and tar executables that you can execute directly from Cmd or PowerShell.
Our cincere thanks to the LibArchive and curl.haxx.se teams who created and maintain bsdtar and curl, respectively.
