What is registry?
The Windows Registry is a database which stores settings and options for Microsoft Windows operating systems. It contains information and settings for hardware, operating system software, most non-operating system software, and per-user settings. The registry also provides a window into the operation of the kernel, runtime information such as performance counters and currently active hardware.
It is important to back up because if your system experiences some problems in the future you can restore the proper registry!
