If you’re looking to uninstall ccleaner from your Windows 10 computer, you’ve come to the right place. Whether you’re switching to a different system cleaner or simply no longer need ccleaner, this guide will walk you through the steps to completely remove it from your computer.

Why Uninstall ccleaner?

Before we dive into the steps, let’s first discuss why you may want to uninstall ccleaner. While ccleaner is a popular system cleaner and optimization tool, it has faced some controversy in recent years. In 2017, it was discovered that the software had been hacked and used to distribute malware. While the issue was quickly resolved, it raised concerns about the security of the software. Additionally, some users have reported that ccleaner can cause issues with their system, such as deleting important files or causing crashes. If you’re experiencing any of these issues or simply no longer need ccleaner, it may be time to uninstall it.

Step 1: Close ccleaner and End All Related Processes

Before you can uninstall ccleaner, you’ll need to make sure it’s not currently running on your computer. Close the program and end all related processes by opening the Task Manager (Ctrl + Shift + Esc) and selecting “ccleaner” from the list of processes. Click “End Task” to close it.

Step 2: Uninstall ccleaner from the Control Panel

Next, you’ll need to uninstall ccleaner from the Control Panel. To do this, go to the Start menu and type “Control Panel” in the search bar. Select “Control Panel” from the list of results and then click on “Uninstall a program” under the “Programs” section. Find ccleaner in the list of installed programs, right-click on it, and select “Uninstall.” Follow the prompts to complete the uninstallation process.

Step 3: Delete ccleaner Files and Folders

Even after uninstalling ccleaner, there may still be some leftover files and folders on your computer. To completely remove ccleaner, you’ll need to delete these as well. Open File Explorer (Windows + E) and navigate to the following locations:

  • C:\Program Files\ccleaner
  • C:\ProgramData\ccleaner
  • C:\Users\YourUsername\AppData\Roaming\ccleaner

Delete any ccleaner files and folders you find in these locations.

Step 4: Remove ccleaner from the Registry

The final step to completely remove ccleaner is to remove it from the Registry. This is a crucial step, as leaving any traces of ccleaner in the Registry can cause issues with your system. To do this, open the Registry Editor by typing “regedit” in the search bar and selecting “Registry Editor” from the list of results. Navigate to the following location:

  • HKEY_CURRENT_USER\Software\ccleaner

Right-click on the “ccleaner” folder and select “Delete.” Confirm the deletion and then close the Registry Editor.


By following these steps, you should have successfully uninstalled ccleaner from your Windows 10 computer. If you’re still experiencing issues or need further assistance, you can reach out to ccleaner’s customer support for help. Otherwise, you can now move on to using a different system cleaner or optimization tool.
