▷ How to open and use regedit windows 10

Its aspect is that of a hierarchical database in the form of a tree where we can find entries with parameters of all kinds that control each aspect of the operation of our system. it is the system itself that performs the management and control of the registry autonomously and completely invisible to the user.

Although this is the case, a user can also access this registry under his responsibility and modify its various parameters. In this way, you can change configuration aspects that are not possible using normal methods that are sometimes useful to solve possible errors, or make them worse.

The command in charge of giving us access to the registry is REGEDIT. We will see how to use it and some aspects that we must bear in mind before touching anything.

Access the registry with regedit Windows 10

To access the registry we can do it in different ways. Windows 10 implements a search engine that we can easily locate from the start. We will only have to write "regedit" in the search box and a search option will appear to execute the command.

Obviously we will have to run it with administrator permissions.

Another more generic form that works for any Windows is the "Run window". To access it we only have to press the key combination "Windows + R" and it will appear. Here we will write regedit and click on execute.

In any of the cases we will obtain the following window, which will be the registry editing environment.

In the window we can distinguish several sections:

Log tree: located on the left of the window we will have all the log entries organized in folders in the form of a tree. Toolbar: at the top will be the toolbar with the actions that we can execute for the log entries. Search engine: just below will be the search engine for records. In this way we can locate a specific record more quickly. Registry entry: the right part of the window is intended to show the different registry entries and values. This is where we can modify these values.

Access a registry entry

To access a record, we must either navigate the tree manually until we locate the entry or we can use the search engine to find it.

The most advisable thing is to put yourself in the hands of the internet or be an expert user to know where the values that may interest us are. After this, obtain the complete path of the key and place it in the search engine.

Let's look for example some entry related to CCleaner that is installed on our computer, but we don't know where it is in the registry.

To do this we go to the toolbar and click "Search…"

Now we write CCleaner and click on "Find next"

You have found a directory in which the name of CCleaner appears. If it is not what we are looking for, we can click again on "Find next…" in the toolbar and it will search for the next entry where this name appears.

This method is not too good if we do not know specifically what to look for. Registration is too long to find something like that. So the most recommended is to know the full route of the entrance.

Modify a registry entry

Continuing with CCleaner, we are going to modify for example one of its registry entries. We have located an entry that controls the updates of this software in this route:

To modify the “UpdateCheck” entry, right click on it and choose the “Modify…” option.

A window will appear where you can change the value of this entry. We are going to put the value 0 instead of the 1 there is. In this way we have deactivated the option to report updates for CCleaner

Create or delete a registration key

In addition to modifying the existing keys, we can also create new keys. To do this, click on the empty space in the input section and expand "New"

Here we select the option we need. To do this we will have to know exactly what we want to do, since there are several types of registry entries. We must be expert users in this type of configuration.

Or we can also delete the entry we have created. For this we only have to choose in the options "Delete"

Actions to consider when using regedit Windows 10

The first is basic, and that is that we should not modify anything in the registry if we do not know exactly what we are doing. On the Internet there are many tutorials, videos and forums where to solve an error they direct us immediately to registration.

We must be aware that they are parameters that affect the system, so before modifying anything we should look for more information about it and see if they have other implications in addition to what they tell us.

Backup to registry

Another very important action that we must do is to make backup copies of the registry. In this way, if we make any mistake, we are still in time to solve it through a backup that we have made before. To do one we do the following:

Full copy

To make a complete copy we go to the "File" menu and choose "Export…"

Next, we choose the directory where we want to store the record and click on accept.

The option of making a complete copy of the registry is not recommended, since there are applications that could be modifying their keys at that moment or system actions. the safest thing is to make a copy only of the key that we want to modify.

Copy a registry key or directory

To do this we go to the key tree and select the specific directory that we want to export. Then we open your options and click on Export. The process is identical to the previous one.

Import a copy

To restore the values before making modifications, we go to "Files -> Import". In this way we select our backup and we will be leaving the values as they were before.

These are the main keys that we must know in order to modify the registry using the Windows 10 regedit command. Always do it with caution because you could be scared.

We also recommend that you read this tutorial before making modifications:
