Tutorial

CCleaner (Crap Cleaner) is a freeware system optimization tool. That removes unused and temporary files from your system - allowing Windows to run faster, more efficiently and giving you more hard disk space. The best part is that its fast! (normally taking less that a second to run) and Free.

Internet Explorer Cache, History, Cookies, Index.dat.
Recycle Bin, Temporary files and Log files.
Recently opened URLs and files.
Third-party application temp files and recent file lists (MRUs).Including: Firefox, Opera, Media Player, eMule, Kazaa, Google Toolbar, Netscape, Office XP, Nero, Adobe Acrobat, WinRAR, WinAce, WinZip and more...

Windows Startup tool.

Features of CCleaner 2.0:
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 cleaningEach scanning process was rewritten from scratch and fully optimized. The result being a noticeable speed increase in all areas.
PortableCCleaner can now run from a USB thumbdrive and be installed/run on a computer without a complicated setup process.
CompactThe rewrite removed all external file dependencies, so the main EXE is now half the size of the original program and support files.
Redesigned User InterfaceThe 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.
ExclusionsIt is now possible to specify files, folders and registry keys to ignore from the cleaning process.
