aero-reg-cube-21icoThe secret to a good optimized windows machine is it’s timely maintenance. For example, defragmentation is something I think brings the best out of your windows machine. Then there is startup applications. I only have the most essential applications starting at the boot time. Well it’s usually stupid and vaguely pathetic to be starting applications at startup unless and otherwise they are really important. However, one of the secrets to keeping your Windows (Windows 7 as well) machine to perform well is to have a slim registry and keeping it that way most of the time.

Windows registry keeps bloating over a period of time and it’s imperative to make sure that you keep it under control by optimizing it on a time to time basis. Now how exactly do we do this is very simple. There are plenty of registry optimizers also called as registry cleaners which are available in the market and today we are going to see Comodo Registry Cleaner which is quite neat and best of all it’s free of cost.
