它是用於刪除不必要的文件和註冊表的最受歡迎的軟件之一，並且根據官方網站的消息，它已被下載超過25億次。它還支持多種語言，並支持在包括中文在內的30多種語言環境中使用。

== 历史 ==
CCleaner於2004年首次在Microsoft Windows上被推出。直到2012年，它仍然是僅限Windows的應用程序。2011年6月2日，Piriform宣布了針對Mac的CCleaner的公開Beta測試程序<ref>{{Cite web|url=https://www.ccleaner.com/news/release-announcements/2011/6/2/ccleaner-for-mac-released|title=CCleaner for Mac [Beta] Released|date=2 June 2011|website=ccleaner.com|accessdate=2020-05-22|archive-date=2019-07-20|archive-url=https://web.archive.org/web/20190720100009/https://www.ccleaner.com/news/release-announcements/2011/6/2/ccleaner-for-mac-released|dead-url=no}}</ref>。 [[macOS|Mac]]版本於2012年1月30日畢業於測試階段<ref>{{Cite web|url=https://www.ccleaner.com/news/release-announcements/2012/1|title=CCleaner for Mac v1.01|date=30 January 2012|website=ccleaner.com|access-date=2020-05-22|archive-url=https://web.archive.org/web/20190720100007/https://www.ccleaner.com/news/release-announcements/2012/1|archive-date=2019-07-20|dead-url=yes}}</ref>。

商業網絡版還被引入。 Piriform於2014年發布了適用於Android的CCleaner<ref>{{Cite news|url=https://features.en.softonic.com/ccleaner-for-android|title=CCleaner for Android: too little, too late?|last=Ferri-Benedetti|first=Fabrizio|date=2014-04-18|work=Softonic|access-date=2017-06-21|language=en-US|archive-date=2016-05-12|archive-url=https://web.archive.org/web/20160512160433/http://features.en.softonic.com/ccleaner-for-android|dead-url=no}}</ref>。

=== 數據收集 ===
CCleaner 5.45的Active System Monitoring組件發布後，包含了一個數據收集模塊，該模塊無需計算機所有者的同意即可從計算機收集信息。 Piriform聲稱它沒有收集個人身份信息。經過批評後，儘管默認情況下仍啟用數據收集，但以後的版本允許用戶分別控制數據收集。<ref>{{cite web|url=https://sensorstechforum.com/ccleaner-v5-45-data-collection/|title=CCleaner v5.45 Introduces Data Collection with No Way to Opt-Out|website=Sensors Tech Forum|date=3 August 2018|author=Milena Dimitrova|accessdate=14 October 2018|archive-date=2019-04-12|archive-url=https://web.archive.org/web/20190412181802/https://sensorstechforum.com/ccleaner-v5-45-data-collection/|dead-url=no}}</ref><ref>{{cite web |url=https://www.ccleaner.com/news/release-announcements/2018/8/30/ccleaner-v5466652 |title=CCleaner v5.46.6652 |website=CCleaner.com |date=30 August 2018 |author= |accessdate=14 October 2018 |archive-date=2020-02-24 |archive-url=https://web.archive.org/web/20200224223059/http://www.ccleaner.com/news/release-announcements/2018/8/30/ccleaner-v5466652 |dead-url=no }}</ref><ref>{{Cite web|url=https://www.zdnet.com/article/cc-cleaner-provokes-fury-over-active-monitoring/|title=CCleaner provokes fury over Active Monitoring, user data collection|last=Osborne|first=Charlie|website=ZDNet|language=en|access-date=2019-06-28|archive-date=2019-04-06|archive-url=https://web.archive.org/web/20190406180209/https://www.zdnet.com/article/cc-cleaner-provokes-fury-over-active-monitoring/|dead-url=no}}</ref><ref>{{cite web|url=https://support.piriform.com/hc/en-us/articles/360010631671-I-m-using-CCleaner-v5-45-Why-is-Active-Monitoring-still-on-when-I-have-switched-it-off-|title=I'm using CCleaner v5.45.

=== 捆綁軟件 ===
據報導，在2018年12月，安裝CCleaner的用戶也將在未經其許可的情況下安裝[[Avast]]防病毒軟件，TechSpot聲稱這可以說使CCleaner並不比它應該防禦的惡意軟件更好。 Piriform否認了這一點。<ref>{{cite web|url= https://www.techspot.com/news/77949-ccleaner-could-install-avast-anti-virus-without-permission.html|title= CCleaner may be installing Avast anti-virus without your permission|website= TechSpot|date= 19 December 2018|author= David Matthews|accessdate= 20 January 2019|archive-date= 2019-10-18|archive-url= https://web.archive.org/web/20191018165019/https://www.techspot.com/news/77949-ccleaner-could-install-avast-anti-virus-without-permission.html|dead-url= no}}</ref>
