You have 100 client computers that run Windows 8 Pro. Each computer has a single local hard disk drive, a DVD drive, and an external USB drive. Each computer has a different set of line-of-business (LOB) desktop applications that are installed locally. All of the applications store their configurations in the HKEY_Local_MachineSoftware registry hive.
