According to nukecad's 1 post in CCleaner Portable Not Available the programming changes in v6.0 caused " a few issues" and a Portable version of CCleaner v6.x likely won't be posted on the official builds page until v6.1 is released next month. I still like the Custom Clean function of CCleaner for disk cleaning and use the Portable (zipped) version to avoid having to install all the unnecessary bloat on my system, but if you try to download CCleaner Portable from the builds page at you are currently offered the previous ccsetup592.zip file. Recall that NortonLifeLock acquired Avira in 2020 and then acquired Avast (including its subsidiary Piriform, the original creators of CCleaner) in 2021, so I expect we'll see more of these "system optimizers" and other bloatware developed by Avira and Avast continue to creep into both CCleaner and NortonLifeLock products in the future. Information about the new Performance Optimizer in v can be found at Our CCleaner 6 App is Out Now With a New, Patented Performance Optimizer and Improved Software Updater. A change log for this major v6.0 release is available at.
