Did you get a Windows Defender error on New Year’s Day?


A number of folks including Dwight Silverman of TechBlog are reporting that on January 1st they were welcomed by the following cryptic error message when they booted up their WinXP computer:

Application failed to initialize: 0x800106ba. A problem caused Windows Defender Service to stop.

The Windows Defender anti-spyware program is a pretty important piece of a computer user’s security arsenal so there’s no question that this message was disturbing to say the least.  The reality is not so bad as Dwight points out, it seems that Windows Defender Beta 2 expired for many on the last day of the year 2006 and you simply need to download and install the final version to reset the timer.  Nice descriptive error message, Defender team.

I didn’t mean they’re stopping support for Windows 2000, I meant that Defender no longer works with in W2000.

For a computer novice like my mom it’s a confusing inconvenience. When I had her purchase the Windows security bundle, it told her to download and install Defender which was a PITA that I ended up completing remotely (LogMeIn) for her. Now, she’s getting system errors and email to upgrade. The security package might work well, but the usability (registration, installation, Defender integration, etc) needs work.

John, I’m not sure where you got your 2000 info. Here’s Microsoft’s stance here in the US… a few more years of extended support which includes security updates:

•On June 30, 2005, the Windows 2000 product family enters the Extended Support phase, which continues for at least 5 years through June 2010.
•Microsoft is not ending support for Windows 2000. During the Extended Support phase, Microsoft continues to provide security hot fixes and paid support but no longer provides complimentary support options, design change requests, and non-security hotfixes.

It’s also important to note that Windows 2000 is no longer supported. Or pre SP2 XP, I believe.

Also if you have problems removing this Microsoft programme from a Microsoft OS (as I did on one of my machines) you’ll need to download the Microsoft Uninstaller program from their website.

Happy New Year!!
