When I tried to copy file into C:\Windows or C:\Program Files, I get the Access Denied error. I belong to the Power User group in Winodws 7. Apart from taking ovnershop of that two folder or change the role of mine to administrators, is that another way which can do copying for this two folder? Please advise?

Hello, Power User group can not use elevated prompt in Windows 7. Please use an administrator account. Also, try disabling UAC.

I have already set "Never Notify" in UAC, is it the same as turning off UAC?

Hi, To perform this operation, you need the administrator privilege. As you have disable UAC setting, if you are no logging on as a administrator account, any changes that require the permissions of an administrator will automatically be denied.
