One of the most powerful tools we have in Windows operating systems is the registry editor through which it will be possible to manage hundreds, or thousands, of configurations and parameters of both users and the operating system itself..
All Windows configuration information is managed centrally in a database hierarchically called Registry, so the registry editor gives us the ability to add and edit keys and values of this registry where we can generate tasks such as preventing access to programs, define functions of some users and many more actions.
How to access the Registry Editor
When we are in the IT support or administration area, almost every day we access this editor using the following key combination and executing the regedit command:
+ R
Within this registry editor we have two fundamental elements that are:
- Keys: These are objects, commonly in the form of folders, in which specific information is stored.
- Values: These are the files that are housed in the folders of the structure of the registry editor
A vital point and that should be taken as a good practice in every place, both at the company and home level, is to create backup copies of these records since if any value is poorly edited we can significantly affect the behavior of the operating system incurring even the formatting of it losing valuable data..
In this tutorial TechnoWikis wants to explain how to create a backup copy of the registry editor and its subsequent restoration if necessary.
