this new best way upgrade npm on windows.

run powershell administrator

set-executionpolicy unrestricted -scope currentuser -force npm install -g npm-windows-upgrade npm-windows-upgrade

note: not run npm -g npm. instead use npm-windows-upgrade update npm going forward. if run nodejs installer, replace node version.
