Windows Defender Errors 0x8024402c 0x80240022 and 1609

Defender1Just installed Giant Microsoft Antispyware Defender Beta 2. Installed nicely, looks pretty, a lot like the Defender that is integrated with the December drop of Vista. However, Defender was unable to update my signatures, instead throwing a COM-ish 0x8024402c. Others are getting Error 1609 and still others 0x80240022.

Word on the street a fix is to remove the Signature Files and reinstall them thusly:

  1. Remove the current signature file. To do this, click Start, click Run, type Msiexec /x {A5CC2A09-E9D3-49EC-923D-03874BBD4C2C}, and then click OK. 
  2. Open Windows Defender. To do this, click Start, click Programs, and then click Windows Defender.
  3. Defender2Check for new definitions. To do this, click the Help options arrow next to the Windows Defender Help icon, click About Windows Defender, and then click Check for Updates. 

While this worked for some, it didn't work for me. I had to visit http://update.microsoft.com to get mine updated. Hopefully this will be fixed soon. I'll update this post as more news arrives.

What program are you using for your power meter?

That's the default IBM craplet that comes with the T42.

The only site which stated a true solution to this issue! While logical I didn't even think of running an update, especially since I installed on three PC's with no issue, but the fourth had the problem.
Thanks!

Same Problem after installation of Windows Defender 2, my error number was: 0x800070422. To solve this issue, I enable
START > RUN > type Service.msc and select OK, restarted Background Intelligent Transfer Service and Automatic Updates. Seem that this Windows Defender will not download updates with either service not running.
