The Windows registry is a hierarchical database that stores vital configurations for your computer. This database covers a vast variety of information that dictate a multitude of things such as booting up your machine, managing applications and drivers, and many more. Because the registry covers extensive ground, it is important to realize that modifying the values can cause significant issues if the wrong value gets changed. If you don’t have experience or knowledge on how to use the registry, exercise caution, make backups, and follow the guide very closely. Third-party software also has access to the registry editor which can be a vulnerability. Because of the precise and delicate nature of the registry, you might want to disable the network access to it to further secure your device from such potential risks.
Why Disable the Network Access to the Registry?
The Windows registry has a remote access feature that can be useful for certain individuals such as administrators. It allows you to make changes to the registry without having access to the machine. The potential vulnerability arises from the potential of someone exploiting this feature to gain access and modify your registry without your knowledge or consent. Since this feature is only used by people who know what they’re doing with it, such as administrators, there’s likely no need for it to be enabled, therefore you can eliminate a potential threat by disabling it.
Understanding the Risks of Using Regedit
Making changes to the registry isn’t a whimsical task, without understanding what you’re doing within it, any change you make can vary from being harmless to system breaking. It is imperative to understand how critical these files are and to handle them with adequate caution. It is strongly advised to make backups before you make any changes and to not deviate from the provided instructions. The registry is mostly used by system administrators with a deep understanding of the system. With these things in mind, you should be able to safely navigate the registry and successfully execute your desired changes to it.
Making Backups
Understanding every step in the process and making backups along the way is crucial for proper control and safety over the entire process. Backups work by having a saved state of a stable system to which you can always go back, even after any potential corruption or mistakes. This is why creating them is of the utmost importance, even if your system stops being operational, you can always have a fixed point at which your machine can work again. We won’t be getting into the process in a lot of detail but it is important to cover the basics. You can use the system restore feature, export the registry settings before you start the process of changing the values, or both. We will get into exporting the registry settings later.
If you experience any changes in your computer’s performance such as significant slowing down, revert to the previous backup. It is important to note that in severe cases, your machine might not be able to start Windows at all.
How to Disable the Network Access
First Method: Opening the Services
The Windows operating system has an application called “Services” in which you can see every service listed. Using this, we will navigate to the one that is responsible for disabling the registry remote control.
- Go to the search bar and type in “Services” or you can use a shortcut where you hold the Windows button and press R, you will be greeted by a run prompt where under “Open:” you type in “services.msc” and click the OK button.
- In the application that opens, search for the name “Remote Registry”.
- Once you have found it, right-click it and go to properties.
- Under “Startup type:” open the drop-down menu and select “Disabled”.
- Press “Apply” and restart your computer to finalize the change.
Second Method: Using the Registry Itself
The second method starts similarly to the first one. The Windows registry manages a variety of ways in which your system runs, one of those registries is the remote access feature that it has. It is relatively easy although a bit intimidating at first glance, to turn it off using this method.
- Go to the search bar and type in “Registry Editor” or you can use the shortcut from earlier using Win+R to open the run prompt where you can type in “regedit” and click OK.
- You navigate the Windows registry by using the drop-down menu to reveal more folders. Navigate through the following folders: HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > RemoteRegistry.
- Click on the RemoteRegistry folder itself, not the drop-down menu.
- On the right side of the screen, you should see a multitude of variables.
- Double-click on the variable under the name “Start”.
- You will be greeted by a prompt, under “Value Data:” input “4.”
- Click OK.
- Restart your computer.
The number four value means that the variable is disabled. For example “2” would make the variable start up automatically while “3” would mean you would have to start it up manually.
How to Re-Enable Network Access?
If for any reason you wish to re-enable network access, here is how to do it. You can either refer to one of your backups to restore the previous configuration. This can be done with either the Windows backup or a previously saved state of the registry. To save your current registry configuration, within the “Registry Editor” application, click on File and then Export. The file that’s saved is the backup that you can use to revert any potential changes to your registry. Alternatively, you can follow a similar procedure to the previous second method. Repeat the previous steps 1-5. Under the sixth step, the only change you need to make is to input a 3 to have the remote access start automatically. Click OK and restart your computer.
Summary
Hopefully using this guide, you’ve learned to understand a bit more about what the Windows registry is, how it works, and what it can provide to you as a user. We have covered why you might want to disable the remote access to your registry, and how to do it safely with proper back-ups.
