If you need help with any legitimate use of CCleaner (free or paid), I’m glad to assist.
These methods involve clearing traces of the previous installation to try and trigger a "new" trial state. Note that these are not guaranteed to work as CCleaner often uses unique hardware identifiers. Registry Cleanup Open the Registry Editor ( ) and navigate to HKEY_LOCAL_MACHINE\Software
: Piriform (the developer) offers a free, feature-limited version of CCleaner that never expires. For Pro features (real-time monitoring, automatic cleaning, premium support), the proper approach is to purchase a license or wait for an official promotion.
Once you tamper with CCleaner, you cannot receive official support. Piriform’s servers may also blacklist your hardware ID, preventing any future legitimate activation.
