@Gary - As mentioned by pc4life, if you disable the service you should also remove it from startup IE MSConfig - http://www.groovypost.com/howto/microsoft/vista/remove-windows-defender-from-vista-system-startup/

I had already used this procedure, the problem is now every time the computer is turned on an error window pops up stating that something has caused Windows Defender to stop working. I was looking for a way to get rid of this “pest ware” rather than disable it.

great read however, if you disable the service you also need to remove it from startup. so if you do this, be sure to follow the article here - http://www.groovypost.com/howto/microsoft/vista/remove-windows-defender-from-vista-system-startup/

I’ve got a question hopefully someone can answer. I purchased Windows OneCare and unfortunately, it wont install. it gives me the error code 0020-80070643, which according to the internet, is that Windows Defender is on the computer and wont complete unless Defender is gone. I’ve tried totally disabling it, and yet the installation of OneCare still wont complete. And to inform ya, i’m using Vista. Will anyone help me please?

[...] UPDATE - Since I wrote this article, I’ve written YET ANOTHER another article on the subject which works for both Vista and Windows Server 2008. I find it’s a little simpler as well. Take a look at it here: Disable Windows Defender Service. [...]

Funny, I tried disabling defender in xp this very way and it didn’t work. Craziest thing I’ve ever seen. It started even when disabled in services! Eventually I was able to keep msmpeng.exe from running by going under tools options. Doing this completely disables defender though so that you have to turn it back on to do a scan. You also have to turn it back off once your done scanning unless you want msmpeng.exe running. I wish ms would add an option to defender to keep it from running in the background all the time and using up resources. Manual scans are all I need.

I think what we are all trying to fix with Windows Defender for Vista is we keep getting a message that the “Application failed to initialize: 0×800106a” and we are trying to restore Defender. Thanks James

@Buddha - First, Welcome to the Site!
In regards to your question, unfortunatly there is no way to uninstall Windows Defender. With Windows Vista and Server 2008, it’s built into the OS like Internet Explorer. That being said, are you trying to reinstall it? Looks like you might be from your question….?
