Microsoft has released the final version of Windows Defender, the Free AntiSpyware from Microsoft.

Download Windows Defender Final directly from the Microsoft site:

Step 2:
Download Orca (a .msi package editor) from here:
Download Orca
Install It.
Step 3:
Open the downloaded WindowsDefender.msi file with Orca.

Step 4:
In the Orca’s left pane, click on CustomAction.

Step 5:
Click on CHECK_WGA.

Right click on CHECK_WGA and select Drop Row.

Step 6:
Again on the left pane click on Dialog.

you guys do such good work, I really appreciate it. I did have a real windows xp I paid for, but ms said it wasn’t valid! anyway, I was wondering, how do I turn on updates? Please tell me step by step, as I’m no computer genius like you guys are.

Umm…Hi, nice to see the screenshot rich step-by-step cracking done with a little bit of creativity. But was this purely an idea of yours? If not perhaps you should accredit the original author :) I know I did that, because its a part of the blogger code.
The second thing is…thanks for your comment on my post, but as my title described it to be “Download,crack and use Windows Defender…the fun and educational way”, I wasn’t exactly preaching malicious cracking techniques to the common mass. Instead I was just pointing out that MS needs to get their guard up, otherwise even noobs like us will be able to infiltrate their software registration procedure.
Good blogging.

How do I uninstall the old WindowsDefender.
When trying to install updates or new WindowsDefender, I get a message that it needs WindowsDefender.msi to uninstall the old version.
Can anyone help?
Thanks Jan
