  • How to Create a Backup of Your Registry? 

Before making any changes to your registry, it is crucial to create a backup of your current registry settings. This way, you can restore your system to its previous state in case anything goes wrong. To create a backup of your registry, follow these steps:

  • How to Use Disk Cleanup for Windows Registry Cleaning?

One of the best built-in tools for managing disk space on your computer is Disk Cleanup. It will clean and remove files that contain data in the registry, even though it does not clean the Windows registry directly. The associated registry entries will also be removed after these data are removed. Follow these instructions: 

  1. To open the search bar, press Win + S.
  2. Enter disk cleanup and press the Enter key.
  3. Choose the system drive and press the OK button.
  4. Select the files you wish to remove by clicking on Clean up system files.
  • How to Clean Windows Registry Through Command Prompt 

Another essential Windows tool that can check system files and images for corruption or other changes is Deployment Imaging Serving and Management, or DISM. Additionally, it can be used to partially clean the registry at the same time. This is how to use CMD to clean the registry in Windows 10:

  1. Use administrator rights to launch the Command Prompt.
  2. To check for corruption in the system image, type DISM /Online /Cleanup-Image /CheckHealth into the command window and press Enter.
  3. Launch DISM /Online /Cleanup-Image /ScanHealth to carry out a more thorough scan and find out if there are any issues with the image.
  4. Use DISM /Online /Cleanup-Image /RestoreHealth to fix any problems that DISM finds.
  • How to Clean Windows Registry via Registry Editor

Using the Registry Editor, you can choose to manually delete registry entries if you are aware of their precise locations. It is important to exercise caution during this process because it is possible to inadvertently remove something important. Here’s how to manually clean Windows 10’s registry:

  1. To open the Run box, press Win + R.
  2. To open the Registry Editor, type regedit and press Enter. 
  3. Use Ctrl + F to locate the key or navigate to the one you wish to delete. You may enlarge the HKEY_LOCAL_MACHINE, HKEY_CURRENT_USER, and HKEY_USERS folders to locate program and app keys.

These are some of the most effective ways to clean the Windows registry. However, these methods need some technical expertise to be executed. So, if you don’t want to get into these technicalities, you can opt for the best registry cleaner software for Windows available online. 

The main advantages of a registry cleaning tool are speed and convenience. Tools are far faster than humans at scanning a system from start to finish and finding a variety of leftover registry entries that have accumulated over time. Usually, the tools display the results as a list, and you can choose which entries to clean.


Following the steps outlined in this guide will allow you to safely and easily clean the Windows registry. Remember to make a backup of your registry files before you continue with the Windows registry cleanup. You can import the backup and restore your registry data if you unintentionally delete some important entries. We hope that by performing routine registry cleaning, you can keep your PC running smoothly.
