What happened to the Power Users group?
In Windows XP, Power User referred to any user account that was a member of the Power Users group. Power User accounts had some, but not all, of the user rights that administrator accounts had. In this version of Windows, the user groups have been simplified and the Power Users group no longer exists. If you upgrade from Windows XP to this version of Windows and you have folders or files that were set up with specific rights for Power Users in Windows XP, you will still be able to use them as you did in Windows XP.
