when the message popped up saying a programme needed my permission to continue (explorer.exe) i pressed the deny by mistake, now i can only access the internet if i right click and and then click on run as administrator. anything i try to access now comes up with access denied, it says to go to system control and change the permission, but this is the only one that it won't let me do this to (the area is grayed and i can't change it from deny to allow). How do i go back to allow this?when i double click to access something i get a pop up saying windows cannot access the specified device, path or file. you may not have the appropriate permissions to access the item.
