I've upgraded to windows 7 RC from the beta and it created a windows.old folder. I've deleted all the files inside the folder that i was able to delete, but couldn't delete the windows and program files folder in there->not able to delete the windows.old folder.
When I try to delete the windows.old folder I get a message "You require permission from administrators to make changes to this file".
I'm an admin and only user on my system and already given myself all possible rights and ownership of the folder.
How can I delete this folder?
