File/Folder permissions in Win7

I am trying to comprehend file/folder permissions in Windows 7. I created a file and a folder(file1 and folder1) and provided both read permissions in explorer.  I placed file1 and folder1 in an Explorer folder with an authenticated, system, administrator, and users with more permissions.  
Problem: I was still able to write to file1.  How do I make file1 truly read only?

If you're just making a file read only, right click on it, and in the attributes check "Read-only" and hit Apply.

If you're a command line type of person:

attrib +r filename.ext

At the individual file / folder level, security is the same as it has been back to NT4 Workstation in terms of how to apply it.

Security has changed in detail and Windows 7 secures main folders like Program Files and such like.

But if you understood file security from earlier systems, it is very similar in Windows 7.

I am still trying understand why after applying read-only permissions to file1 and placing it an Explorer folder with higher permissions....why my read-only did remain for file1? Is it an inheritance issue from the folder?

If permissions have been applied to an individual file before placing in a folder, placing in that folder does not change the files permissions. You can set file permissions to what you want as was noted in an earlier post.

If by default, if you copy a file to a folder (or move a file from another volume) the file will inherit permissions from its parent.

To remove the default permissions, you have to go into Security > Advanced and break inheritance (uncheck "Include inheritable permmissions...") to keep the parent permissions from automatically applying.

Richmondj...The "Include inheritable permmissions..." is grayed out.  I can not uncheck it.

Is there a "Change Permissions..." button?  If so, you have to hit that first.
