These freeware programs, such as OpenOffice.org and RoboForm, just keep getting better with age
Perhaps no program has evolved more over the years than Piriform's CCleaner, which began life in 2003 as "Crap Cleaner." True to its name, the tool scours your PC for unwanted crud that accumulates in Windows' arteries: temp files, Registry fragments, log files, browser cookies, and so on. Then, with one click, it clears all that stuff away. No wonder CCleaner remains one of the most popular system-optimization tools ever.
