It is of utmost importance to repair a corrupted Windows registry correctly to ensure a system’s stability, speed, and to restore overall performance.
The Windows registry may become corrupted by poorly configured applications, a bad installation, computer viruses or invalid registry entries.

When repairing a corrupted Windows registry, either manually or with the assistance of a registry repair application, it is essential that you perform a backup in the likely event that additional damages occur.
Repairing your corrupted Windows registry is a scary task. Despite the Windows registry being a vast hierarchical database storing sets of functions for all software installed on your system, you can conduct repairs to restore your PC to an optimized state, but first you need to identify the corruption on your registry to better understand what kind of registry repairs are needed; therefore, we recommend you use a registry repair tool to fix your corrupt registry and increase the performance of your computer.
What is Windows Registry?
Program updates, installations and removals, and configuration settings are all information that is kept in the Windows Registry. This information is stored as registry keys and values, which correspond to a particular process or program. Some of these keys need more space to be stored and some of them need less, but all of them take up space in the registry. Since the registry contains vital data needed to maintain the normal operation of a Windows system, its functions need to be well known in order to repair any registry errors that occur in it. If the registry sustains any damage, your machine may be disabled. If the registry is not cleaned on a regular basis, it can lead to serious system problems and poor computer performance. You may experience slow computer work and/or frequent program crashes.
Signs You Have a Corrupted Registry
There are several symptoms that identify your computer as having a corrupted registry. Many of these signs may be first identified during the startup of Windows. Do you ever notice any error notifications when Windows is attempting to load an application or system driver? In most common situations, registry corruption can be solved by scanning your registry to detect and repair specific registry issues.
Over time, regardless of how your computer is used, the registry can become corrupted. Many times Windows will let you know when corruption has occurred. The Windows registry is a complicated structure that often times renders an error message. This is Windows way of telling you that something is wrong and needs to be addressed. Registry corruption errors are sometimes identified by a simple alert notification. Other times a registry corruption issue is the result of a setting within Windows being changed or degraded system performance. Below are symptoms that identify a corrupted registry.
- You notice settings in Windows have suddenly changed without your interaction.
- Receive error notifications after startup related to the Windows system folder missing a file or having a corrupt file.
- Receive error notifications related to a “Registry File Failure”.
- Receive system error messages with an executable file name listed, ie: “System error: Lsass.exe”
- Receive an “access denied” notification when attempting to access a file or folder that is normally accessible.
Registry Repair Steps to Manually Clean Your Windows Registry
If you want to check the current state of your computer’s registry and avoid any registry problems, it is recommended that you run a registry scan with the registry cleaner. However, if you decide that you want to clean your registry manually, you have to be extremely cautious when doing it. You have to remember that the registry includes registry values, which are essential for running all of the programs on your PC and vital for the OS to run normally. If you delete the wrong registry entry, it can result in failing to load Windows. For that reason, you cannot remove random entries, but you have to carefully check the responsibilities of every key before deleting it. Caution: Because of the sensitive nature of the deletion process, it is highly recommended that you use a registry cleaner to safely remove registry errors. A registry cleaner will help you find and repair any registry errors. To access your computer’s registry and browse it, you have to go to the Start menu, click on Run, enter regedit and the Registry will open.
Once you enter the registry, you can remove entries corresponding to files and programs. This option can be used if there is some application which is installed on the PC but it is not possible to remove it using its installation file. However, if you want to remove it in this way, this can confuse Windows and may result in trying to load the program on system start up. To fix the problem, the folder of the program in the registry has to be found. The folder together with all the files of the program have to be removed to fix the problem.
It is important to know that before trying to clean your registry or fix any current problems you have to make a backup of your registry and its entries. To backup your registry manually, you should run regedit.exe, choose File, then Export. Make sure that you click All radio button in the Export range field.
There is also another option that is to copy only single registry entries. This can be done again from the Start menu and the Run tab. You have to enter regedit and then press OK. Once you have entered the program, you have to find the subkey you want to copy and click on it. Open the File menu and then choose Export. The final step is to save the file to a location that you prefer. The saved file will have the extension .reg which corresponds to Registration Entries.
Reduce System Start Up to Boot Windows Faster
To make Windows boot up faster, you should decrease the number of your registry keys that are checked on system start up. When the system starts, Windows checks every registry entry. This process is done in order to organize the configurations of all the programs installed on the computer. On system shut down, computer’s registry is again checked and if there are any errors this operation may take longer than usual. For that reason, any registry errors have to be fixed as soon as possible in order to keep the smooth work of the computer. Time-Saving Repair Tip: To avoid further inconvenience, you can use a startup manager to automatically reduce the amount of time it takes your system to boot rather than having to check manually the key yourself, especially if you don’t know exactly which entry you need.
If you would like to repair some registry errors, you have to find them in the registry. A backup of the particular file has to be created and only then the value can be deleted. There is a chance that when you restart the computer the OS will repair the missing file automatically on start up. Another option is to use the installer of the program to update the file.
