I think it is great you update as often as you do, but is it really necessary to visit the webpage to download the installer, and then run it, every time. I understand if you get paid every time someone visits your site, since the program is free, but can't it be a simple redirection after you have installed an update? I mean, it is so much easier clicking one button to close it, rather than going through a few just to download the installer. No disrespect meant of course.
You can always grab it from FileHippo, which only requires you click once. http://filehippo.com/download_ccleaner/
This is a feature of the paid version (auto-update with the option of silent)
That is true, auto update is built into the pro version. You can get that here: http://www.piriform.com/ccleaner/download
