npm update -g 1.5.0 equals errors

Hi I have seen a couple of these posts and none are really working for me, as soon as I install npm or update it shows these errors.

npm ERR! Windows_NT 6.3.9600

and when I want to install or add anything from ionic it show this.

'ionic' is not recognized as an internal or external command,
operable program or batch file.

I have tried npm clear cache and reinstalling ionic but still does not worked.
Also this only happened after updating npm, thank you.
