Today we will talk about system registry optimization. I will tell you what the registry optimization is, what the Windows registry is, what slows down the system, how it can be fixed.

First of all, we should start from what causes the Windows operating system to slow down. It is all caused by fragmented system registry files, removed and unnecessary registry entries remaining in files. Now let’s take one at a time.


It occurs when a file is located on difference disk sectors. As a result of adding new part to, updating and overwriting files, their parts may be saved to different sectors that are located quite far from each other. It reduces the rate files are read at. Imagine that you have a large stand where you keep a lot of various literature (a book is a file), but not as regular books, but as separate chapters. Moreover, the first chapter may stand on one shelf, while the second one is on another shelf in the corner, the third one is on the third shelf in the middle, and the forth one is located on the forth shelf between two chapters from a completely different book. Not to get lost on the stand, you have a general plan where you can see the place of every chapter of every book. Now here’s a task for you – read some book. You take the plan and start reading the book, chapter by chapter moving from shelf to shelf searching for each next chapter. Of course, it will take a lot of time and you will quickly get tired. The same occurs in the computer in case of defragmentation. To read one fragmented file, the hard drive head has to move a lot over different sectors collecting bits of information from different disk parts. It takes a while. The operating system slows down in this case.


As you can judge from the name, it is a process opposite to fragmentation. It means that the chapters of one book are arranged on one shelf in the proper order. Now imagine that you are standing near this stand and read a book like this. You will spend considerably less time on searching for the necessary chapter and the total time you will need to read the book will be reduced. The hard drive head also finds information faster in the computer and, as a result, the system works faster.

Microsoft Windows system registry

It is the heart of the operating system, it stores all settings and configuration of the operating system and a lot of software installed on the computer. While running, the operating system (or various programs) very often accesses the registry and reads and writes data. The registry is stored in regular files located on the hard drive. Of course, the registry files get fragmented because data is often read from them and written to them. As a result, the entire system slows down. Imagine that you have to read books from a stand where all chapters are randomly scattered all the time. Do you imagine how much time it will take?

System registry defragmentation and compression

System registry defragmentation means defragmenting the system registry files of the operating system. But you have to compress the registry files first.

What is registry compression? Registry compression comes down to deleting unnecessary and removed entries, which results in reducing the total size of the system registry. The registry files get considerably larger after the Windows operating system runs for a long time. It is mainly caused by installing and removing all kinds of software. When you remove unnecessary entries from the system registry, they are only marked as removed, but they still exist in it and occupy space. Besides, a lot of absolutely unnecessary data that just fills it up appear in the registry with time.

What can you use to compress and defragment the registry?

There are a lot of tools on the Internet that can clear unnecessary entries from the registry. But very few of them can defragment the registry. I would point out two programs that support the defragmentation feature: Registry Mechanic and Reg Organizer®. Both programs are good and do their job well. The difference is that Reg Organizer® has more powerful features.

    I seldom perform this tasks on my computer. But reading this post, I will definitely do this for my computer.
