C:\windows\system32>npm i -g npm@latest
npm ERR! code EEXIST
npm ERR! path C:\Program Files\nodejs\npm.cmd

npm ERR! with --force to overwrite files recklessly.

Solution

1. Run CMD(Command Prompt) as administrator
2. Uninstall and reinstall Node.js version using nvm (un)install <version>
3. Open an explorer window and open C:\Program Files\nodejs directory
4. Install specific version of npm (globally) using npm i -g npm@<version>
5. After the installing process has started, delete or remove the following files

- ‪C:\Program Files\nodejs\npm
- ‪C:\Program Files\nodejs\npx
- ‪C:\Program Files\nodejs\npm.cmd
- ‪C:\Program Files\nodejs\npx.cmd

The following is an example of a successful installation (update).

C:\windows\system32>npm i -g npm@latest
C:\Program Files\nodejs\npm -> C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js
C:\Program Files\nodejs\npx -> C:\Program Files\nodejs\node_modules\npm\bin\npx-cli.js
