  1. Click the Windows 10 start menu at bottom left, and start typing 'environment'
  2. You'll see this menu item "Edit the System Environment Variables", select it
  3. A System Properties window will open up. You will see a button "Environment Variables" just click it
  4. Then select the path variable, and click the Edit button
  5. Click the Add button, paste in the folder path where you have unzipped the curl package or where curl.exe resides
  6. Click Ok as needed. Close all the open command prompt windows and reopen it, so they get the new path location for curl

Now enjoy typing curl at any command prompt in Windows
