Defrag the Registry with Regdefrag - gHacks Tech News

Defrag the Registry with Regdefrag

The Windows Registry is not defragmented if you defragment your hard drive. This can be quite a problem for users who regularly install and uninstall applications on their system because uninstallers tend to "forget" to remove entries in the Registry during the uninstallation process.

It's astonishing that even the Registry of my brand new system which has been setup only a week ago was highly fragmented.

Defragmenting the Registry with Regdefrag  reduced the size of the Registry system from 28904 Kilobyte to 27160 Kilobyte which is a reduction of more than 6%.

A smaller Registry file will speed up the time it takes to boot into Windows which is why it is recommended to defragment it regularly. While you won't see improvements while the system is running, it is nevertheless a good practice to do it because of the boot speed improvements.

I remember that the Registry on my old computer had a size of 55 Megabytes, that's twice the size of the current Registry.

The process or defragmentation works exactly the same way as the defragmentation of a hard drive by removing gaps, fragments and wasted space in Windows Registry files.

defrag registry

Analysis and defragmentation did only take a matter of seconds on my computer, it probably will take longer on slower computers with a larger Registry but won't be near the time it takes to defragment a hard drive.

The program itself is easy to use. Simply run it and either hit the defrag Registry button right away, or start with a click on get Registry information instead which displays how large the Registry it but not its fragmentation status.

A click on the defrag button highlights the entire process on the next screen. The program analyzes the Registry first and displays results on the next screen.

There you may then hit defrag again to start the process or click cancel to exit it.

Update: RegDefrag has not been updated since 2010. The program seems to work fine though in recent versions of Windows

    You really should read what defragmentation is. To defrag a hard drive means to put the bits of a specific file together on the physical medium. The Regdefrag authors simply call their process ‘to defrag’, but it is not the same process. Regdefrag removes unnecessary entries, it does not rearrange the entries that are there. They are taking a technical term and turning it into a marketing term. That’s disgusting.

    The only 2 REAL registry “defragment” programs I know of are:

    Pagedefrag – http://technet.microsoft.com/en-us/sysinternals/bb897426.aspx

    and

    NTRegOpt (actually compact only function) – http://www.larshederer.homepage.t-online.de/erunt/

    OK. Fine. What should they call it? It’s still a useful utility. And considering Quicksys offers it for free, why should whatever they call it be considered “disgusting.”

    This software doesn’t remove invalid registry entries. It does an internal registry desfragmentation, reallocating the empty spaces from previously removed entries in order to leave it contiguous, so wasting less space and making it faster. So, yes, it really does what it tells. You can read more in the FAQ session in the RegDefrag website. ;-)
