Cache Cleaner

Cache Cleaner is a lightweight and portable piece of software with a pretty self-explanatory name - it allows you to clean the computer's memory easily, whether you are an advanced user or not.
Since Cache Cleaner does not come with a setup pack, you can simply drop the executable file on any spot on the hard drive and directly run it.
It is also possible to store the app on a USB flash drive, external hard drive or similar storage unit, in order to run it on any computer. Plus, you can keep it in your pocket whenever you're on the move.
What's more important is that the Windows Registry is not updated with new entries, and no leftover files can be found on the hard drive after program removal.
The interface of Cache Cleaner is represented by a very small frame with a plain layout. The "what you see is what you get" principle clearly applies to the tool, as there are no other features available, aside from the ones visible in the main frame. So, you can check out the current and peak size of the memory cache, and clear it with the simple click of a button.
The application is very low-demanding concerning the CPU and system memory, so it doesn't interfere with the runtime of active processes. It has a good response time and swiftly clears the system memory, without hanging, crashing or popping up error dialogs. All in all, Cache Cleaner is a pretty straightforward program, although it has not been updated for a very long time.
