However, let’s offer a solution to those interested

  1. Open a Terminal window with administrator privileges.

  2. Change the directory to the one where CCleaner is installed (e.g. C:\Program Files\CCleaner).

  3. Run the command Ccleaner64.exe /export. Three ini files are created in the directory.

  4. Run the command notepad.exe winapp.ini. This is the content of the file in my case
