Following installation of nodejs managed by nvm for windows, I cannot run the node and npm in the Windows PowerShell unless run the PowerShell using administration access.

For Windows 10, Windows 7, Windows 8, Windows Server 2008 R2 or Windows Server 2012, run the following commands as Administrator:
x86 (32 bit)
Open C:\Windows\SysWOW64\cmd.exe
Run the command powershell Set-ExecutionPolicy RemoteSigned
x64 (64 bit)
Open C:\Windows\system32\cmd.exe
Run the command powershell Set-ExecutionPolicy RemoteSigned
Now, node and npm can be run from the Windows PowerShell as normal user, no need administrator privileges.
