What are the Best Ways to Clean the Registry on a PC

The Registry is a collection of valuable keys and values that holds the information on configuration settings required to run applications on the PC. When you install an application, its configuration settings will be stored in this Registry. After uninstalling, these registry files usually aren’t deleted and may remain inside them as a broken or missing key.

Registry cleaning is a necessary task for keeping your PC running properly. It can help you fix problems with programs and their settings and keep your computer organized and immune to viruses and malware.

In this blog, we will now discuss removing these unwanted files from your Registry to maintain your PC’s performance.

Methods to Clean Registry in PC

Before getting into cleaning the Registry, you have to take a backup. Because the Registry contains the crucial files for the programs to work correctly, you cannot use those programs if you delete them. Therefore, you must take a backup before using the Registry Cleaner process to be safe. Follow these steps for a registry backup:

  • Press the Win+R keys and enter regedit to open the Registry Editor menu.
  • Go to File and click on Export.
  • Choose a location and select All in the Export range option to back up the entire Registry.
  • Click on Save to complete the process.

Now you are good to proceed with cleaning the Registry using the following methods:

Windows Disk Cleanup

Windows has an inbuilt Disk Cleanup Utility, which enables you to clean residual files from all the storage drives. It doesn’t specify the removal of registry files, but it deletes all the residual files and folders left over after uninstalling applications and drivers.

To use this method, go to search in the taskbar or start menu and type Disk Cleanup. Now the utility runs an automatic scan and shows a menu that lists the unwanted files stored in your C drive.

To scan other drives, you can click on the Cleanup system files option to find files from other areas of the PC.

Then, select all the files you want to delete and click OK. Your system is now clear from Residual files, and this would have cleared some parts of the unwanted registry files.

Manual Cleaning 

If you need only specific areas of the Registry to be cleaned up, you can use this method. But beware of deleting registry keys of existing applications as it may ruin the program entirely. Before deleting any registry, you can take note of the keys and values to recreate it.

Press Win+R and type Regedit to enter the Registry Editor. Choose any folder and Right Click. You can either expand and scroll through the list to find the app you want to delete or click find and enter the application’s name.

Once you find the specific folder of your application, now right-click and press delete to remove the registry files related to that app.
