The Windows Registry is a central database that stores huge amounts of settings for just about everything your operating system does. From changing the way the desktop looks, or information about all the devices and drivers, to registration information for your programs. You don’t need me to tell you just how important it is that for a smooth running system, a fully functioning and error free registry is one of the most important factors. Just a few rogue values inserted into some important registry keys can bring your system to a grinding halt or turn it into an unstable nightmare.
Because a lot of malicious software will attack various parts of the registry, and just about everything you touch causes reads or writes to it, making sure it is backed up is still an important way to keep problems and downtime to a minimum. There are also times when you are going to reinstall your system and would like to transfer some settings on to the new operating system. Things like registration information for software like perhaps a Giveaway of the Day program or a highly customized look for your desktop could do with being copied to save a lot of time.
