Windows 7: How to remove (reset) all security files/folder permissions?

I have a problem with my security permissions. I need to reset all security permissions of my files/folder to reconfigure this. What I have to do?

Um, that is not that easy. You are lucky if you can run a system repair via the install disk, and if they will be fixed.
If you are talking about private files/folders, there is no way to do a restore, have you used the 'take ownership' command?
Please tell a lil more about the details.

I solved changing the owner of the folder!

I'm beginner in Windows 7. I never used the security settings before!

Thank you!

If you are a beginner, you should be changing security settings...there is no reason to do so.

You don't! Leave them alone.

This is one of those cases where Father Microsoft knows best.

I was not clear, sorry! I will be more clear now:

I have a document folder with many sub-folders and files and I wanted protect this folders from deletion from other user accounts of Windows! The other users may execute this files but not delete. I changed the owner of the folder and now the users can not delete this files.

Thank you again!

One additional word of caution.

Taking ownership has given you protection against standard users, but you should be aware that anyone with admin privilege can simply Take Ownership themselves, and access the files.

There are methods to truly protect these files but they are fraught with danger as you may end up locking everyone out from the files including yourself, (this involves removing all privilege from all users except your own user, but as you are a member of the administrators this can be problematic).

As long as you are the only administrator with access you should be safe but I would suggest you also backup the files regularly to a different location for full protection

I'm the only user with admin privileges and I do backup every day!

Use Icacls to find out who has what rights to the files you own.

Ownership only means that you can a) give someone else ownership, b) set/reset/remove the access rights of others.

True, you can also use the properties | security feature of Windows to view and alter. I just prefer the command line.

same problem i faced...what i did was i deleted all contents of that secured folder and then restore all images and folders of that folder...and now i've full access to my images and folder. BUT only 90% images restored..... it would be better to restore them on other location initially and then store them where u want.
so its better to have some thing rather than nothing..
