The excellent registry cleanup tool Quicksys RegDefrag is now available in version 2.0. It features a new registry scan algorithm, improved Windows 64-bit performance and multi-language support among other additions.

The Registry cleanup tool quickly scans the Windows Registry to find gaps, fragments and wasted space and displays a quick report after the Registry scan that outlines the gain from defragmenting the Registry.

A smaller Registry has several advantages including a faster system start and an overall increase in system performance. It is necessary to close all open software programs before starting the Registry scan.

RegDefrag provides access to automatic System Restore Point creation and Registry backups before starting the defragmentation. Both can be configured in the program's options.

A html report can be created in the end which provides an in depths summary of the Registry cleanup process. The computer system has to be restarted before the changes take effect.

Update: The official program and developer website is no longer available. It returns a not found error when you try to open it. We have removed the link therefor from the article, and suggest that you use an alternative instead as you may run into compatibility issues eventually due to lack of updates.

A free alternative is WinASO RegDefrag. It optimizes the Registry in three steps. It scans the Registry in the beginning, displays the result of the analysis in the second step, and leaves it up to you to go ahead with the defragmentation.

The program supports a quick defragmentation option which takes about a minute to complete, and a full defragmentation which takes up to ten minutes but often has a more positive effect on the system.

The application displays the size reduction in the report. If it is in the Megabyte range, you may want to go ahead with the defragmentation to speed up the start of the system.

    simpler, load Autoruns (SysInternals)
    – filter “Defender”
    – untag all entries
    – reboot
    nothing has changed since my 1st modification years ago

    I wouldn’t disable Defender imho, it has too many hidden roots inside Windows itself. One time I tried to uninstall it using brute force scripts and then the Onedrive feature stopped working definitely. A reinstallation was needed and since those times I prefer to maintain Defender untouched. It’s a better method to install another antivirus and it will disable Defender in a safer and easier mode (e.g., Avast is the best in this way, and also Panda Cloud Free is good too).

    You can not stop defender from running in background or remove it without some penalty. All you can do is to limit telemetry.

      @borts,

      It’s probably Smartscreen which is preventing WD from being disabled. Get rid of that and the problem should be solved: https://thegeekpage.com/disable-windows-defender-smartscreen/#How_to_disable_the_Windows_Defender_SmartScreen_via_Local_Group_Policy_Editor

      Linux sucks dude. Besides it’s not comparable to Windows, these OSes are in different classes entirely.

        I use Linux as my daily driver. It’s far more stable than Windows. When’s the last time you used Linux, 2010?

Dudebro, it’s no way near as cool as Windows with its hardcoded abilities to make money off the user, bro. Yo brodude man, you’re the coolest dude ever man, bro. Dude.

    Download Autoruns and remove the checkmark from Windows Defender. It doesn’t remove it, but it will never run. https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns

    Per this video,
    https://www.youtube.com/watch?v=CLIjr7FyxZ8

    Win Defender, is completly the most succesful free-built in antivirus of Microsoft. Really nice product. Saved my ass a lot of times. Has updated malware database, completly strong defence
    from whatever smart screen disables. Or if you want better and more upgrated (paid) program,
    you can go further. But defender is always on your side.

    Why would one disable Windows (or Microsoft) Defender in the first place?. I consider this to be playing with fire big time. Everybody knows that if one is using another A-V, Defender will be disabled on its own and won’t be in one’s way.

    Why would I want to disable Windows Defender in the first place? It’s a great anti virus in my opinion. Been using it since Windows 8 and and never had a problem or a virus. Why mess with a good thing, if it ain’t broke don’t fix it.

    How a ridiculous article!
    I am thoroughly stunned.

    Why Should You Disable First-Party Windows Defender?
    I can only think that it is “malice or perversely intention (want you to buy a third-party AV where you can expect a back margin)” to guide invalidation without showing the premise.
    No sane company will use third-party closed source programs (such as AV).

    As I thought, “Ghacks Technology News” seems to be coming to downfall.
