The registry is a kind of DNA of Windows computers as it keeps a record of every task performed on the system like opening a file or document, installing and uninstalling programs, etc. However, Windows will never remove registry entries even if a program is uninstalled. Most of the uninstallers do not have the nature to remove their own registry keys.

So, the registry gets loaded outdated entries which can cause error messages and slowdown computer speed and performance. Therefore, it is very much important to clean registry in order to boost system speed, free up a bit more storage space, and reduce startup time.

Booting up, opening and closing programs, everything starts taking extra time as your operating system searches for relevant information in a registry full of errors and trash. That is why it is advised that you keep cleaning up your Windows registry periodically or after installing and uninstalling programs, but mostly for the stabilization.

There are two ways to clean your Windows registry and optimize the system to speed up your computer. The first one is using the registry editor and cleaning the registry keys manually. It is also quite time-consuming as well as risky. You might end up with a completely broken and dead system.

The second and the better method of cleaning up your computer registry is running a registry cleaning software. If you want to slim your system, do not just download a registry cleaner, but an all-in-one computer clean and optimization tool, like Neptune SystemCare Ultimate. The program will automatically scan and repair all the errors in your registry, restoring it back to a perfect condition. This is the quickest and easiest method of getting your whole computer back to an almost new condition and increasing its speed. If you want to use Neptune SystemCare for that sole purpose, you need to launch Registry Cleaner under System Cleaner.

You can also run Registry Defrag every three months, for further PC clean. Head to System Tuneup to run Registry Defrag.
