Try running the cmd with administrator privileges.

Also If your user name contains some space say "Firstname Lastname" then run this command inside "C:\Users> DIR /X". It will give you the link name for your user. copy the link name which would be something like "FirstName~1".

Before updating verify the "npm get cache" contains any empty space or not. If yes the do this,
"npm config set cache C:\Users[Your link name without the bracket]\AppData\Roaming\npm-cache"

Try running the cmd with administrator privileges.

highly recommend not doing this.

Would like to know the complications of the same. Why is it not recommended with administrative privilege?

It opens up security issues. You are basically telling any node module you install that it now has admin rights.
