Hello everyone. This is my first post, so please forgive me if I put this in the wrong area. I noticed when running CCleaner that I had 5GB of Windows log files created on my computer. This has built up several times over the last week, and each time I cleaned it with CCleaner. I was unintelligent and didn't actually look at what was logging that much (I will next time), but is there any way to stop such a large volume of logging from happening? Is it normal for Windows 8?

Thanks for you help.
