Sooner or later, each user comes to the stage when he has a desire to speed up the computer. At this stage, he gets acquainted with the basic methods that can help him achieve what he wants. One of the easiest and most effective ways to optimize the system is to clean and defragment the registry. Knowing how to use this tool is especially important if Windows has been running for a long time without reinstalling.
What is the registry and what actions can be performed with it? The system registry is a large
information field that stores all the basic data used in the operation of the system. This includes installed settings, a complete list of programs, their components and much more. In the course of its activities, Windows many times per second makes queries to this database. Naturally, the
installation and removal of programs, as well as other elements of the life of the operating system, increase the amount of data contained and contribute to the accumulation of various “software junk”. These "remnants" and begin to interfere with the normal functioning of the computer.
In order to correct this state of affairs, it is necessary to periodically conduct procedures such as cleaning and defragmenting the registry. Cleaning can be done independently, or you can use specialized software. As for programs to remove various unnecessary elements of the system, there are quite a lot of them. A simple search on the Internet will help you choose a free assistant to perform this function.

To clean manually, you should write the command "regedit" in the line that is called through the "Start", "Run". As a result, the "Registry Editor" opens, where you need to select the section containing the word "user" at the end of its name. Usually this is the second folder on top. In the list that opens, you need to find the "Software" directory. It is there that many unnecessary elements of existing and remote programs remain. By searching, you can remove any of these components by pressing the “Delete” key.
Defragmenting the Windows 7 registry, however, like other versions, is a very important point in optimization. It is impossible to carry out this process manually, therefore software should be called for help. Most modern programs allow you to plan this action, performing it every time before loading the system or after certain intervals.
In order for this important process to be successful, it is necessary to know and take into account several points.
1. While the program for defragmenting the registry performs its main function, all other programs must be closed.
2. The procedure may be accompanied by a freeze of the computer, discoloration of the image on the monitor, etc. If such situations arise, you should simply continue to wait. In no case should you resort to any action, as this may adversely affect the final result.
It is very important that the registry is cleaned and defragmented regularly. This will help keep the system clean and speed up your computer.
