When I right click on C: (or any folder in Explorer, really) and click
Properties -> Security, I'm unable to apply changes to any administrator
permissions. I get two pop-up messages: "An error occurred while applying
security information to: [name of folder]. Access is denied.", and "Unable to
save permission changes on [name of folder]. Access is denied." One is a
generic Windows error, and the other is a Security Error.

Help!

Hi Askrenes,

You will probably need to take ownership of the item before you will be able to modify it. You can see how to do it here:

Take Ownership of file
