We have a bespoke application that requires changing the file permissions of the c:\windows folder, at the moment I cannot find a user that will allow me to do this. Please can anybody tell me if this is possible and if so how to do it. Cheers

Hi, I suggest running Windows Explorer with administrator privileges. Right click Windows Explorer icon on taskbar, in the jump list, right click Windows Explorer and run as administrator. If you still cannot change the permission of the file, please contact the support of the application or modify the application if it is designed by yourself.
