Complete rebuild in C++
With the requirements for a portable version, 64-bit compatibility and Windows Vista increasing against the limitations of the old architecture. We decided to rebuild the entire CCleaner application in highly optimized C++.
Faster analyzing and cleaning
Each scanning process was rewritten from scratch and fully optimized. The result being a noticeable speed increase in all areas.
CCleaner can now run from a USB thumbdrive and be installed/run on a computer without a complicated setup process.
The rewrite removed all external file dependencies, so the main EXE is now half the size of the original program and support files.
Redesigned User Interface
The original CCleaner user interface was looking a little dated, so the GUI was redesigned with a modern look, but without sacrificing speed or usability.
New icons were created for the interface and the main program icon was updated with a more modern style.
It is now possible to specify files, folders and registry keys to ignore from the cleaning process.
Loads of little tweaks
Too numerous to mention them all separately, we've tried to improve CCleaner in all areas.
