nodejs LTS v6.10.2 Windows installs give npm version 1.4.2 instead of 3.10.10

I have tried uninstalling and installing nodejs LTS v6.10.2 on Windows multiple ways but I keep getting ((npm version 1.4.3)), even though it says it should be 3.10.10.
I have used the Windows installer (.msi), trying both 32 bit and 64 bit (my machine is 64 bit).
I have also tried installing using the Windows binary (.zip).
I have not tried the build (because of its additional requirements).
"NPM -VERSION" reports 1.4.3.
"Where NPM" reports the correctly installed location as "C:\Program Files (x86)\nodejs\npm.cmd" after the 32 bit install and "C:\Program Files\nodejs\npm.cmd" after the 64 bit install.

Maybe the user authorization is the main reason?

I found it.

The .npmrc file (in c:\users{userid}) contained a PREFIX line pointing at an older version of node/npm in a Rational Application Developer (Eclipse) environment. And it was surviving my uninstall/reinstall .

Once I deleted the line, then I started getting the new version.

prefix = C:\Program Files\IBM\SDP\cordova_cli
