No specific info about version 4.3. Please visit the main page of CCleaner on Software Informer.
Could be better, must be free for a full featured version.
My friend Heather told me how good CCleaner is.
A very useful tool to help with keeping your system clear of files that tend to affect your system's performance. The application is constantly updated, and has proven to be an invaluable utility in my arsenal for maintaining my system's performance.
