A few weeks ago, I did a review of CCleaner. It was also an in depth look if anyone was also interested in that. Recently, there has been a CCleaner update that came out, and it adds one thing that is really important -- full Windows 8 support. If you run CCleaner, you will get an alert about another update being ready, but you can also check for updates by going to the about area of the software.
The change log release can be found here. Let me know of your thoughts on this.
