Update Anaconda Navigator 1.5.0

I had trouble updating Anaconda Navigator from 1.5.0 to 1.5.2 in Windows 10. While there was a message indicating that the update was successful, the version remains. Gladly found the solution here: https://github.com/ContinuumIO/anaconda-issues/issues/1583 :

1. Open command prompt
2. Execute:

   C:¥> conda update --all --prefix <path_to_the_installed_conda>

That's all :)
