Simply the best free registry cleaner, CCleaner supports both Windows 32-bit and Windows 64-bit. It cleans up temporary internet files, history, cookies and other junk left behind by hours of web surfing. By doing that, it also cleans up your tracks.
CCleaner has also recently added support for an array of different programs likely to be running on your system like Audacity, Silverlight, BitTorrent, Google Chrome, CuteFTP and TONS more.
The latest version of CCleaner also runs faster than previous versions, though older systems still obviously run much slower than a PC with more resources.. it goes without saying.
CCleaner will empty your recycling bin, backup the registry before 'cleaning' it and overall speed up your Windows experience. Much more important in our opinion than cleaning up Internet files is its powerful registry cleaner. Not only can it remove references to unused libraries (DLLs), but it also removes references to non-existent programs and fonts, it cleans up installer issues, activex issues and more.
Another wicked tool is the hard drive wiping tool. It removes all data from a selected hard drive. You can choose to do a 1-pass 'scrubbing' or more. A 'Gutmann' 35-pass wipe of the hard drive will really get in deep and remove traces of files which once existed. There are different levels of wiping the drive and even a 1-pass will get the job done if you're not hiding something too important. Drive scrubbing can also be limited to free space on the system. One note about drive scrubbing, the more passes you select, the longer it will take to complete the task.
If ever I have a buddy who complains above a slow start up or even just a sluggish experience on their PC, I always download CCleaner and run it for them. I always get a thanks afterwards, but the thanks should go to the guys at Piriform for such a lightweight, simple, yet powerful program that lives up to the task.
Overall, whether it's for a buddy or yourself, CCleaner is certainly a must-have system utility for all PC users. If you find this tool useful, you can donate to the developers on their web site.
Another lovely point about the program is that it contains no spyware or other unwanted rubbish like toolbars or that change your browser homepage or default search engine.
Environment variables have been added for %SystemDirectory%, %SystemDirectory32%, and %SystemDirectory64% for support on systems running a 64-bit copy of Windows. The latest version also improved on Chrome, Firefox and Safari cleaning.
CCleaner can effectively clean the registry and free up disk space.
