If you do not protect your windows account with a password then any other method will not work as the people will still be able to log in into your account and thus access everything else anyways as if they were you.
Unless you use a 3rd party program to encrypt/zip/whatever your folders you want to protect, but that would require more than simply 1 click...
In the end, simply adding a password to your account is the most easy and effective solution without messing around with other stuff.

This is much different than what you said before in context of the fastest/easiest solution...
Protecting just 1 file is something entirly different than being able to protect whole folders and several files and what not, on the fly or without much clicking and messing around.
If it is just 1 file, a file which you don't access that much, simply compress it and password protect it with an archive program.
