I use this utility. Temp File Cleaner

But a few things I've to warn you:
First when install, choose custom install and unmark the fort two options ( set temp file cleaner DB as......). Freewares have a certain tendency to install toolbars nowadays. It's part of the sponsorship programs.
If you've a TEMP folder with your own temporary files (I create these temp folders where I store files that are not still classified) be sure to unmark the option "Root
Temp", otherwise the utility will erase all your files in your Temp folder. Yes it happened with me when I run it for the first time. But because I've always installed an utility to recover delete files in my machines, I end up having no problems in recovering those files again.
Before you get used to the program I advice to do a test run, and there you'll check if there's any file in the generated log that you didn't intend to delete it.
I usually don't use the advanced options.
It's a perfect tool for deleting superfluous temporary files. Run it once in a month routine.
And look at your Flash player settings.

I know, know.... It's too much info for a Neanderthal computer-wise. But you asked.
By the way you aren't a Neanderthal computer-wise. I know them very well. You aren't one of them. You're more XIX century type, and you're leaning how to use the steam.
In that scale I'm learning the secrets of mass production with Henry Ford.
