Boot Faster: Defrag+Compact Your Windows Registry

How does internally defragmenting and compacting my Windows registry help my computer boot faster?

Windows Registry Keys

The Windows registry is a database that stores settings and options for Microsoft Windows operating systems.

Data is stored in the registry in hundreds of keys and sub-keys.

Your registry contains information that Windows continually references during operation, such as:

  • profiles for each user;
  • the applications installed on the computer;
  • the types of documents each application can create;
  • property sheet settings for folders and application icons;
  • what hardware exists on the system;
  • and the ports that are being used.

As you operate your computer, Windows and programs constantly query the registry for information. As programs are installed and uninstalled, your Windows registry becomes internally fragmented from the addition and removal of registry entries.

Over time, the registry ends up with a lot of blank cells. When new items are added to the registry, these blank cells remain unused, causing the registry to grow much larger than the size of the actual data it holds.

A bloated registry results in:

  • slower boot time;
  • slower system operation;
  • and slower application performance.

To reduce this bloat you must defragment and compact the registry, which will result in faster system access to your registry settings and faster Windows operation, including start up!

  1. There are many free and paid programs that can clean up un-used registry leftovers and then compact registry hive to make it smaller. Which means, the registry hive gets smaller and faster to load and does not consume memory when its gets “defragged” or “compacted”.

    Is there any comparison test Raxco Perfect Registry versus many free ones available on the net? Is there any significant boost to operating system boot time when using Raxco Perfect Registry or when using a free one which does the same?

    1. Hi Seppo. I understand your concern however there are two points that stand out in your question. 1. You mention free software. It’s what you’re getting alongside the free software that cannot be verified and is a concern. What price are you paying to install the “free” software? Security? Privacy? If you have no concerns about the free software then the next question is: how aggressive is your alternative registry cleaner and can you undo the registry cleaning from your free (or paid) software? (which brings me to the second point.) 2. PerfectRegistry provides the unique option to backup and restore existing registry settings prior to a registry defrag and compaction, so that you can effectively “undo” an aggressive defrag and compaction if needed.
