Install Windows Defender Bypassing Genuine Windows Validation

Windows Defender which previously known as Microsoft AntiSpyware, is free software utility from Microsoft that is designed to prevent, remove and quarantine spyware on Microsoft’s Windows 2000, Windows XP, Windows Server 2003, and Windows Vista operating systems. Windows Defender can be downloaded free from Microsoft Download Center, and currently released as Beta 2. It will be integrated into future versions of Windows Vista, and can be run with all users with or without administrative privileges.

Microsoft has protected Windows Defender from possible software privacy on Windows OS by implementing dual layer of WGA validation check when downloading Windows Defender Beta 2 and during installation of Windows Defender, although many strongly believes that it should be provided free to protect Windows users from harming other Windows users. For suggestion of how to skip the WGA validation to download Windows Defender visit here, or download Windows Defender Beta 2 x86 English version from direct download link or 64-bit English version direct download link here.

After downloading Windows Defender, there is another Windows Genuine Advantage Validation check on your Windows product key. If you’re unable to pass the test to get your copy of Windows validated, you will get the following message:

To install this software, you need to obtain a valid Windows product key. Contact Microsoft Product Support Services using the options provided on the Microsoft Help and Support website.

WGA genuine check is attached to the Windows Defender Windows Installer package. TechTics has found that with Orca, which is a Microsoft utility for modifying and validating Windows Installer .msi packages, and intended for setup authors and administrators that works with the Windows Installer Service, the part for the genuine Windows check can be dropped and disabled. Orca is available in Windows Installer SDK which is part of Windows Server 2003 Platform SDK, and can be download here, or here, here or here for Orca only (shorter download).

  1. Download Windows Defender.
  2. Download Orca.
  3. Install Orca.
  4. Open WindowsDefender.msi in the Orca.
  5. In the Orca’s left pane, select InstallExecuteSequence.
  6. Right click on the Action CHECK_WGA and select Drop Row.
  7. Click OK to continue.
  8. Save the Windows Installer .msi file.
  9. Exit Orca.
  10. Install Windows Defender.

Alternatively, you may download the patched and fixed version without WGA product key validation here and here. The trick or the crack should allow you to download updates for Windows Defender too.

  • No need for stupid Orca :

    Just using these command from Run box was enough, smoothly installed Windows Defender: No need for Validation or Registry Tweaks or Patch or Bypassing:

    Simple CMD & Clean Installation was successful:

    C:WindowsDefender.msi -qr

    Thanks you:

  • Orca.exe hostfiles have been deleted please re-upload them. Thanks

  • no se puede descargar el orca ya no esta si alguien me lo pásara o m dieran otro link de antemano gracias mi mail almarazfrank_2@hotmail.com

  • despues haz click en inicio—ejecutar y escribe esto

    “c:/WindowsDefender.msi -qr”

    (la extencion "qr" es para quiet mode o no interaccion de usuario) de esa forma el instalador saltara la verificacion del WGA e ira directamente a la instalacion ;)

    gracias son mas que bienvenidas…

  • argh…i cant find the CHECK_WGA…where is it?

  • Yes the last one worked !!!

    Awesome man

    Thanks

  • I think you don't have to hack or modify anything to install Windows Defender.

    AutoPatcher XP (only for SP2) includes Windows Defender inside. You can get a copy of AutoPatcher XP here:

    h**p://www.autopatcher.com/downloads/

  • i cant find the action CHECK_WGA where is it?

  • my Windows Defender Version: 1.1.1593.0

    is not updating.

    it says the program cant check defination updates

    “error found: code 0×80004002″

    plz give any solution

  • sorh thanks u. i can install Windows Defender but i cant update error found: code 0×80004002

  • Useing above way to skip WGA check, it works well for installing and updating. But for taking Removing action when want to remove spyware, it shows:

    Error encountered:

    Code 0×80508027. This copy of Windows is not genuine. To receive the full protection of this program, you must verify that your copy of Windows is genuine. Until you successfully validate your copy of Windows, this program will only remove certain threats. Only users of genuine Microsoft software get access to the latest updates, features, and product support.

    Does anybody know how to get full protection?

  • This will skip WGA Check altogether

    Table: ControlEvent

    Dialog: InstallWelcome

    Control: Next

    Argument: Change CheckWGA to LicenseAgreement

  • thanks qually….worked perfect.

  • Yeah this is awesome. Thanks guys.

  • The latest Windows Defender's msi can be hacked!

    Open the msi with Orca and go to ControlEvent. Next find the CheckWGA. Then swap the conditions in lines with Arguments "LicenseAgreement" and "SetupCompleteWGAError".

    Works as designed. LOL

  • thanks – the controlevent fix works

    Windows Defender Version: 1.1.1593.0

    Download link removed due to complaints from Microsoft

  • Install and updates work correctly but i cannot apply any actions to detected faults.

    Returns code 0×80508027 Genuine version of windows is required to use all functions of this software….

    Anyone else have this problem and/or a solutions?

  • Used your Orca method to install final version of Defender over the Beta 2 version. It worked flawlessly. Thank you for helping me keep from getting infected and infecting others on the WWW. May the virus writers all come down with some strain of flu for the holiday season and be bed ridden.

  • Ok, I found the workaround for october 24′th version ( WindowsDefender_1.1.1592_FINAL ) here:

    It’s something like this:

    Just open Windows Defender in Orca, open the ControlEvent table, then go to the InstallWelcome dialog, and change the one that has the event CheckWGA to LicenseAgreement. This makes the Welcome page skip the WGA page completely, and go straight to the license page.

    It works … for the above noted version.

    Enjoy!

    Request: Just for students who don't have money to to buy costly XP.

  • If you get this error after bypassing the CheckWGA

    in ControlEvent

    “The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. Error code is 2356″

    after it almost finished, it's probably because

    you saved the WindowsDefender.msi as a different name after you mod'ed it in orca. It has to have the same name ..WindowsDefender.msi

  • Thx Chris & Alex. Both solutions are in working condition with current latest release:

    WindowsDefender_1.1.1592_FINAL (october 24'th 2006, I think).

    Although Chris's one is more direct, both are OK.

    ;)

  • Nice tip Alex, however there's a similar but better method.

    Just open Windows Defender in Orca, open the ControlEvent table, then go to the InstallWelcome dialog, and change the one that has the event CheckWGA to LicenseAgreement. This makes the Welcome page skip the WGA page completely, and go straight to the license page.

    Similar to the above method, but skips the WGA page entirely.

  • The new Windows Defender is out, the way to bypass the WGA check (at least the one I found) is to open the MSI with Orca. Click Control Event on the left and go to CheckWGA. Make sure that the Argument column of the first and second CheckWGA Dialogs is "LicenseAgreement" and you can install and use Windows Defender without problems.
