Problems While Running CCleaner For Windows

CCleaner For Windows

Popular junk file cleaner CCleaner can clear system caches, surfing histories, log files, troublesome registry keys, and other items. It can also delete unwanted files left behind because of uninstalled apps.

But many users complained that CCleaner is showing numerous problems on the Windows system. Due to all such consistent issues, many users shift to alternative mac cleaner and Windows cleaner apps.

Let us know and study in detail about all the problems users face while using the CCleaner application.

Issues Occurring While Using CCleaner

Below are the various types of errors CCleaner creates and disturbs your workflow on the Windows system. This section can assist you if you’re having trouble with how CCleaner is cleaning.

As well as if it’s causing a security or antivirus program to send a warning or if you’re experiencing some specific problems with Windows user profiles.

Selected folders or files are not getting cleaned

You must instruct CCleaner that you wish to clean specific files and directories in addition to adding them to the Include part of the Options menu.

Before running a clean, you can perform the following in the Custom Clean section:

  1. Select the Custom Clean option in CCleaner’s left-hand menu.
  1. Choose the Custom Files and Folders box under the Windows tab’s Advanced section.

When cleaning, CCleaner reveals that some things are left out

CCleaner recognizes that the running programs are often browsers. As a result, you are asked to shut them. This is because CCleaner needs your permission to shut down the running apps.

CCleaner cannot ask for this permission or close open browsers. This happens if you have selected the “Do not show me this message again” option.

You can still get prompts for this information even though the browser(s) seem closed. This can happen if they are still running in the background.

Please go to the Options > Advanced menu in the software and select Restore default settings if you want to enable the display of these dialogues once more.

The Include/Exclude lists and the Cookies to Save list are both completely cleared from the software’s settings. Although you can ask CCleaner to shut open browsers once more when these prompts appear.

On your computer, you cannot delete any other user accounts

On your PC, CCleaner Free just cleans the user account that is currently logged in. You must subscribe to CCleaner Professional in order to clear other user accounts. After upgrading, go to Options > Users and choose different user accounts.

When you launch CCleaner, a User Account Control message pops up

Modern versions of Windows use the User Account Control (UAC) feature to prevent users from unwittingly launching spyware or malware. Also, to stop making significant modifications to the way Windows functions.

When you’re about to launch specific programs, it will prompt you for confirmation to accomplish this. There’s a chance you’ll see a UAC warning when you launch CCleaner. Click Use CCleaner Now to proceed.

If you encounter a UAC warning when using the program, please check the CCleaner Options > About section. Look to see if the Skip User Account Control Warning checkbox is active. As default, CCleaner instructs Windows not to display a UAC warning.

Even though you didn’t want to, some files are destroyed

No version of CCleaner has an undo feature; doing so would essentially defeat the software’s purpose by making it impossible for it to reduce the amount of storage utilized on the system and create it so that these “undo files” will include the exact private information you are attempting to obliterate for reasons of privacy.

You see a firewall or antivirus alert

When an unidentified application begins to request access to the computer’s files or the internet, they monitor for unusual program behavior and notify you.

You might get a notification on either of these apps if you launch CCleaner for the very first time after installing them on your computer. When CCleaner looks for an update, you can additionally notice an alert. To allow CCleaner to proceed, click Allow under the warning.

Set an allowance for CCleaner in the security tools to stop receiving any additional notifications from it regarding the program, or if the notice does not say Allow. You might have to do this in many places depending on the type of detection done.
