With disk cloning software, as we have already discovered, the entire system as it currently stands (including the operating system, all user data and any installed software) can all be copied over to a new PC with very little fuss. This process is often time consuming at best and potentially very costly if the installation media for certain software is unavailable, often resulting in the need to re-purchase the application in question thus taking up time and adding even more cost to a system migration! One of the biggest problems with acquiring a brand-new PC is that all user data must be migrated over from an older, existing PC and any Windows applications which are in-use must also potentially be re-installed, re-licenced and reconfigured. Yes, this ability to copy applications which are already installed upon an existing system is one of the main reasons disk cloning software has become so useful, but let’s consider a common example to get more details on how this might actually work.
