Free Registry Defragmenter to defrag Windows Registry

The Windows Registry is a database, located in the system32 folder, that stores all system configurations and settings.  Over a period of time, you do end up installing and uninstalling several software on your computer. many a times, you tweak or change system settings, and change them back – all this can result in broken registry keys, orphaned keys and invalid entries in the Registry. Moreover, when you remove such invalid registry entries using a Registry Cleaner, empty spaces are left behind in the Registry and its hives.

Free Registry Defragmenter

Registry Defragmenters help in removing such bloated registry hive & empty spaces, and compacting the registry. We have already seen whether Registry defragmentation is useful or not. If you do decide to use a Registry Defragmenter to defrag Windows Registry, here are a few free one’s that you may want to check out.

Auslogics Registry Defrag

The registry is very much like hard disk drives. Whenever you start working on your computer, programs access the registry very often. Due to addition and deletion of entries, the registry may develop invalid entries and get bloated and fragmented over time. To an extent,  a fragmented registry could reduce computer performance. Auslogics Registry Defrag can defragment and compact the Windows registry in less than a minute. The program will scan the registry, remove slack spaces and also reduce the size of the registry. The program also offers to delete your junk files. It appears to be the only freeware which offers a nice UI and shows you the fragmentation of the registry. It also automatically creates a system restore point first before starting the operation, which is a good thing in my opinion.

I have used this registry defragmentation freeware on Windows 7 and Windows 8, on occasions and found it to be pretty safe.

While installing this freeware, do remember to uncheck the options to make Ask your default search provider and Ask.com your home page.

NTREGOPT is a registry optimization software which was popular during the Windows XP days. Its current version is compatible with Windows 7 , but  will only work correctly if you turn off User Account Control and run it with proper administrative privileges.

PageDefrag

PageDefrag from Sysinternals will defrag Paging & Registry files. Standard defragmentation programs can neither show you how fragmented your paging files or Registry hives are, nor defragment them. Paging and Registry file fragmentation can be one of the leading causes of performance degradation related to file fragmentation in a system. It uses advanced techniques to provide you what commercial defragmenters cannot and that is the ability for you to see how fragmented your paging files and Registry hives are, and to defragment them.

PageDefrag has not been updated since 2006 and therefore may not work on newer versions of Windows.

Apart from the above-mentioned registry defragmenters, many software like TuneUp Utilites, SpeedUpMyPC,  PowerSuite 2013, Auslogics BoostSpeed – as also some free Windows Optimizers include a Registry Defragmentation software as a part of their suite.

Do let us know if you use Registry Defragmenters or would like to recommend any particular one.
