When I go to remove 'read only' status from a Windows folder?

when I go back to check and see if it worked, it ALWAYS is back to 'read only'?

Here's the process.

1) I right-click on the folder to be changed.

2) I scroll down to properties and left-click.

3) On the window that pops up, under the 'attributes' header that pops up, 'Read only is highlighted.

4) I left-click on the box and it's no longer highlighted.

5) I left-click the 'apply' box in the lower right corner.

6) I left-click the 'OK' box a couple spots to the left.

7) I right-click on the folder, scroll down to properties, left click to open the window, and when it comes up THE 'READ ONLY BOX IS HIGHLIGHTED AGAIN!!!!

WTF am I doing wrong?

Note: This is NOT restricted to system folders; this includes folders I create to organize files and even my Internet Favorites file (which means it won't let me replace or delete old internet links).
