RamCleaner is a free shareware RAM optimizer application that is available from Benutec Software's web site under the category of "memory optimizer" and developed by a former Microsoft engineer. The review for the application has not yet been completed, but the reviewer here on a Windows Vista PC was able to run it with no issues. This is probably due to the fact that the software is built around a technology called the Window Registry Cleaner technology which allows the application to use a "registry database" of files and settings in Windows to speed up the operation of the system. In simple terms, the application will make changes to the registry in order to get rid of unwanted, unused, and damaged registry keys. This is how the application makes a claim to be able to improve the speed of your computer by reducing the size of the Windows registry and also improving the performance of the Windows XP operating system.
The main complaint about this application with Windows XP is that the applications do not seem to be compatible with the version of the operating system that I am running, although the program is easy to use and seems to work fairly well. The only problem that I have noticed with the application is that I can sometimes get error messages when it has been used to clean the Windows registry. However, after I fixed the problems that I was having with the program, I did find that it did in fact make a difference to the speed and reliability of my Windows XP PC.
The best recommendation that I have for anyone looking for a good tool for speeding up the Windows XP operating system is to download and use the program that works best for you. If you are on Windows XP, then you should try the free trial version of the program before you purchase it. Many people have found that this software has actually improved their computer's speed. However, if you do decide to purchase the product, then make sure that you have a back-up of all your important information like passwords for internet banking, emails and online banking etc. so that you can roll back any changes that you may have made if anything goes wrong. You could be left in a worse situation than before.
