"npm install -g newman" command is not working for installing newman in windows

Question

Installation fails using

• node -v v10.16.0
• npm -v 6.9.0

This is the output

The operation was rejected by your operating system. It's possible that the file was already in use (by a text editor or antivirus), or that you lack permissions to access it.

If you believe this might be a permissions issue, please double-check the permissions of the file and its containing directories, or try running the command again as root/Administrator (though this is not recommended).

Try running the command prompt as admin.
