Does anyone know that Power User Group in Windows 7 how to copy files into C:\Program Files and C:\Windows Folder? Thanks,

Power user group does not exist in win7. http://windows.microsoft.com/en-US/windows-vista/What-happened-to-the-Power-Users-group In Win7, Trusted Installer is the owner of files and folders under c:\windows folder, so you might have to give your account ownership of files and folders and then copy files in to it. A member of the Power Users group may be able to gain administrator rights and permissions in Windows Server 2003, Windows 2000, or Windows XP http://support.microsoft.com/kb/825069 Manoj Sehgal

So there is no other way besides taking ownership from the Trusted Installer to local administrator and copying the files?
