i was trying to rename a folder but windows won't let me. it seems like it thinks that the folder is still in use by another program however all the programs that use it have been closed. when i rename it at first i get a window with a title "Destination Folder Access Denied". the text in the window is as follows: "You need to confirm this operation". after i click Continue i get another window with a title: User Account Control and text: Windows needs your permission to continue and then the first window pops out again, which at this point i click "Try Again" but this window keeps coming back. how can i fix this problem?
