If your computer is running slow, there are a few things you can do to get it running faster again. One of the things you can do is use something called a registry cleaner. A registry cleaner will go through your computer's registry and delete old or unused files and items. If you're looking for how to clean up slow computer with registry cleaner, search through some websites to find more information on them.
The registry is the database that collects and stores all the information and settings on a Windows based operating system. Many times when a computer encounters errors, these are stored in the registry, such a when a program does not finish installing, information that is no longer needed.
Sometimes programs that have been downloaded leave files in the registry that don't completely delete when uninstalling. Malware also leaves files in the registry that can be hard to get out. A registry cleaner will go in and remove the unwanted or unused files and broken links. This can improve the computer's performance by cleaning up the files.
Use caution though, because spyware will often diguise itself as a registry cleaner. If spyware gets into your system it can disguise itself as a popup that prompts you to download a so-called registry cleaner that will only unload viruses and malware on the computer. Be sure you are dealing with a reputable program when using registry cleaners.
Also, poorly designed registry cleaning software can actually damage the registry by removing key entries that should not be removed. Be sure to research the cleaner you are using first before attempting to use it.
There are many things a registry cleaner cannot remove, as well, so it should not be used as a cure all tool. In the end a registry cleaner should only be used as part of an entire system, along with antiviral software and anti spyware, to keep your computer running smoothly.
