node command not found and NVM_SYMLINK not set properly by auto

[yaochiqkl]

My Environment

• Windows 7 or below (not truly supported due to EOL - see wiki for details)

• Windows 8

• Windows 8.1

• Windows 10

• Windows 10 IoT Core

• Windows Server 2012

• Windows Server 2012 R2

• Windows Server 2016

• My Windows installation is non-English.

I have already...

• read the README to be aware of npm gotchas & antivirus issues.
• reviewed the wiki to make sure my issue hasn't already been resolved.
• verified I'm using an account with administrative privileges.
• searched the issues (open and closed) to make sure this isn't a duplicate.
• made sure this isn't a question about how to use NVM for Windows, since [gitter]

My issue is related to (check only those which apply):

• settings.txt
• proxy support
• 32 or 64 bit support

Expected Behavior

I've installed nvm-windows succussfully through installer.
node and npm can be used in command

Actual Behavior

nvm use xxx works well.
it shows Now using node v6.9.5 (64-bit)
But node and npm doesn't work showing command not found

settings.txt

root: C:\Users\HP\AppData\Roaming\nvm
path: C:\Program Files\nodejs

when I check the C:\Program Files\nodejs, it points to the wrong version of node C:\Users\HP\AppData\Roaming\nvm\4.2.1,which I didn't installed by nvm but installed early before nvm installed.
And it never change after running nvm use 6.9.5.

---

NVM_SYMLINK points to C:\Program Files\nodejs
but C:\Program Files\nodejs points to wrong version and never changed.
Tried through administrative privileges but in fail.
