In the event of a mechanical failure or data corruption on the Operating System drive in the PC the “system image” can be restored to a new HDD and your PC can be back up and running in an hour or two, complete with all data and programs intact. This image can be used as a complete disaster recovery option (as long as the image is not stored on your operating system drive). Full hard drive backup can be performed by choosing the “Create a system Image” option. The only limitation on Windows 7 Home Premium Edition is that it cannot backup data to a network location such as a network-attached storage device (NAS), another PC on the network, or to a network server. Backups can be automatically scheduled by the user to any frequency they like. The Backup and Restore centre was first introduced in Windows Vista and provides users with the ability to back up files, folders, libraries or even their complete hard drive. Home Premium: Limited to local HDD or DVD Professional: Local HDD, DVD and Network No performance improvement was evident when moving from 8GB to 16GB, therefore I do not see the 16GB physical memory limitation of Home Edition to be an issue when choosing an operating system. Recent tests of a mid range Windows 7 based PC with configurations of 4GB, 8GB and 16GB of system memory have shown only a marginal overall performance benefit between 8GB and 4GB. Home Premium: 16GB of physical memory supported Professional: 192GB of physical memory supported
