How to let other computers see ONLY the public folder?

I used to have messed up file sharing settings because the printer wouldnt work but they were alright because whoever looked into my Computer in the network would only find a Public folder. (w/o passwords)

Now, i reinstalled windows, and whenever somenoe looks into my computer under the network, they have to enter a password and once they do, they can access not only the public folder, but all my documents under my folder. (Users/MyStuff)

the sharing folder is Users so people can see everything inside Users if they have my password.

What i want to do is let them only access the Public folder WITHOUT my password.

That way, if i have something that needs to be transferred, i'll just drop it on in the public folder, and someone can take it.

I am confused in terms of how to reach these settings and i would appreciate it if anyone could offer a solution.
THank you.

Disable Homegroup and have a good Public and Private key Encryption.

homegroup is off (i left it) and i clicked on my folder, went to "Share with" and clicked "Nobody" but it is still viewed on the network if they have my password

Thanks it worked ! ! ! ! ! ! ! ! !! +rep to both
