Der Ccleaner löscht sowohl Spuren vom PC, die man sich beim Surfen im Internet einhandelt, als auch etliche Verlaufslisten, die etwa entstehen, wenn man Dokumente öffnet. Bei der Reinigung von Surfspuren unterstützt das Tool unter anderem den Internet Explorer, Firefox und Opera . Außerdem räumt das Tool die Registry auf und sorgt so für eine gleich bleibend hohe Systemperformance. * With the requirements for a portable version, 64-bit compatibility and Windows Vista increasing against the limitations of the old architecture * Each scanning process was rewritten from scratch and fully optimized * 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 * 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 * It is now possible to specify files, folders and registry keys to ignore from the cleaning process * Loads of little tweaks Latest Changes: * Fixed bug where some IE Temporary files were not removed * Fixed bug with IE7 Recently Typed URLs cleaning * Fixed C++ exception on Desktop shortcut scanning * Installer now works on 64-bit OS Recycle Bins menus * Optimized IE Temp files cleaning speed * Improved index.dat cleaning on XP * Fixed Registry Cleaner as "Fix All" sometimes wouldn't work * Keyboard shortcuts now work correctly in Registry section * Files winsys.ini and winreg.ini are now embedded in the EXE * Fixed bug where Autoupdate check could cause an exception * Fixed minor bug in restoring screen position and size * Lots of internal improvements to reliability and speed * Minor UI tweaks
