How to maintain your Windows Registry

Background Information

The Windows Registry is a set of files that contains settings for your Windows PC - such as what program to use to open HTML files, when your antivirus program should run, or what desktop background you use.

Over time, the Registry can become cluttered with missing or broken items as you install, upgrade, and uninstall software and updates. CCleaner Cloud's registry cleaner can help you clean out the Registry so you'll have fewer errors. The Registry will run faster, too.

To clean your Registry:

  1. Log in to CCleaner Cloud > Choose a computer
  2. In CCleaner, click the Registry icon on the left.
  3. Optionally, select the items under Registry Clean you wish to scan (they are all checked by default).
  4. Click Scan for Issues. You'll see a progress bar and a list of potential issues.
  5. Once the scan is finished, you can review the list of issues. Click Fix selected issues... to fix the Registry problems.
  6. CCleaner Cloud will backup the Registry first. You can find information on restoring this below.


Restoring Registry entries removed by CCleaner

Registry entries that are removed by the Registry Cleaner in CCleaner Cloud are automatically backed up on the machine that was cleaned.

To restore these, go to the Computer and browse to:

My Computer > C Drive > Program Files (x86) > CCleaner Cloud > Backups


If you have run a registry clean, you will see a file called ‘RegBackupFile’. Double click the .REG file you wish to restore and the registry entries will be imported.

Note: Only the registry entries from the last 5 cleans are backed up
