Want to clean and optimize your PC? You've probably heard of CCleaner, arguably the world's most popular tool for doing the job. It clears out temporary files, cleans the Windows Registry, erases browser histories, and so on.
Developer Piriform just released CCleaner 3.0. The big news in this update? A native 64-bit version for use with like editions of Windows.
CCleaner 3.0 also sports new icons, various interface improvements, better support for Google Chrome and Internet Explorer 9, and newly added support for programs like AVG AntiVirus 10.0, Audacity, LogMeIn Hamachi, BitTorrent, and Windows Game Explorer.
I particularly like the way it intelligently scans for cookies you'd want to keep, like those for Google and Yahoo.
In short, the ultimate system-cleaning tool just got better. It's still free, thankfully, though you can purchase a priority-support license for $24.95.
As with any tool of this kind, I strongly recommend making a full system backup and creating a new system-restore point before using it. Better safe than sorry!
