Perhaps the most significant drawback to using CCleaner on Windows 11 is the security and privacy implication. In 2017, CCleaner was acquired by Avast, and shortly thereafter, the software suffered a malware injection incident. While the breach was resolved, it damaged the trust of the user base. Furthermore, the free version of CCleaner has become increasingly aggressive with pop-up advertisements and bundled software installations. In contrast, Windows 11 is built with a "security-first" mindset, featuring Windows Defender (Microsoft Defender) as a robust, integrated antivirus solution. Relying on a third-party cleaner that requires deep system access arguably widens the attack surface of a secure Windows 11 installation. windows11 ccleaner

Among these, Piriform’s CCleaner has long been regarded as a staple for PC optimization. However, the release of Windows 11 marked a significant shift in the operating system's architecture, security model, and built-in maintenance capabilities. This evolution raises a critical question for the modern user: In an era of sophisticated built-in tools and heightened security awareness, does CCleaner still have a relevant role to play in the Windows 11 ecosystem?

Consequently, the functional gap that CCleaner once filled has narrowed significantly. For the average user, the disk space savings provided by CCleaner—often a few gigabytes at most—are negligible on modern Solid State Drives (SSDs) with capacities starting at 256GB or more. The perceived performance boost from cleaning these files is often a placebo effect on modern hardware, where the primary bottlenecks are usually CPU and RAM limitations rather than storage clutter.
CCleaner (originally "Crap Cleaner") rose to fame during the Windows XP and Windows 7 eras. At the time, Windows was less efficient at managing temporary files, system logs, and uninstalled application remnants. CCleaner provided a centralized, easy-to-use interface to:
