Upgraded but npm -v still returns old

[TS22082]

It seemed to have updated, I got a success message, but when I ran npm -v it still says old version. Any help would be appreciated.

Checked system for npm installation:
According to PowerShell: C;\Program Files\nodejs
According to npm: C;\Users\ts220\AppData\Roaming\npm
Decided npm is installed in C:\Program Files\nodejs
upgrading npm...

Upgrade finished. your new npm version is 6.5.0. Have a nice day!
PS C;\Windows\system32> npm -v
6.4.1
PS C;\Windows\system32>

I have the same issue. Its because my npm is here: \AppData\Roaming\npm in windows 10. It upgrades the c:/program files/nodejs which isn't the one actually used.

Look at your according to NPM line
