I notice you said;"I had my Windows 7-64 bit re-installed. Now, all my work files and folders are "read only"."
Was this done for you by work or a shop?
If you haven't already gone back to whomever did this for you to get a quick guide to your files I can tell you how to add yourself as the owner again. Make sure you read this through first and apply only if you feel your comfortable doing this. Do not do it to Program Files, Program Data, Windows, or any other files/folders that are part of the system.
Note: This is ONLY for the files and folders that are yours as a user, not for system or trusted installer folders/files as it will break your system or render it unbootable!
Go to the file you want to change permissions too, or folder if its one you created like "stuff" or "movies" and all files inside are again your users.
Right click on the file/folder and select security, then advanced. You should see tabs at the top just like the security or details tabs on the prior window.
Select Owner, at the bottom right choose edit, select your user name and then click on the bottom right apply or okay. (I'm not on a windows machine at the moment so exact button/tab names will be best guess.)
You can now tab over to the permissions window which has all the users who are allowed to use this file/folder. I always add my user name if missing and then give myself full control. When saved this should return you to being the full owner and user with all rights to the file/folder.
(Note: if a folder you will need to apply to all sub folders if you want to save some time and extra work but I find it's not 100% successful. If I wanted to delete all files in a folder and did this sometimes I have to manually go to the files and do it again anyway...but that's usually when I'm taking control of system files/folders.)
