CCleaner opens on its own unexpectedly on my computer.

Hello.

To close any stubborn application, simply right-click on a blank space in the quick launch bar at the bottom of the screen, and click on "Task Manager."

A new window opens where the relevant program appears. Just click on it once to select it, then click the "End Task" button to close it.

The easiest way to stop receiving messages from Ccleaner is to disable its automatic startup when the computer boots up. This won’t prevent it from functioning normally, but it will no longer display any messages and it won't update automatically either. In exchange, it will no longer take up memory space, which you can reclaim for your applications.

To disable it, click on the Start button => Settings => Apps => Startup. In the list of applications that launch at startup, only those related to the computer's components (sound card, video card, or processor) and security (antivirus, antimalware, or firewall) are necessary. Everything else can be disabled.

Disabling programs does not prevent them from functioning. They will no longer occupy memory space (some programs like Ccleaner are only used once a week for regular use, but currently consume memory continuously).

In terms of use, the only difference is that they will no longer update automatically and will take a few tenths of a second longer to start since they are no longer preloaded in memory.

If you continue to use Ccleaner, you will see that the first thing it does when you launch it is to update itself before anything else. And this is true for all programs.

Disabling a few programs should give your computer a little boost.

Best regards
