I uninstalled Windows Defender ages ago as soon as I realized that it had just been hogging the CPU. For some reason, an error message pops up on startup:

"The application failed to initialize: 0x800106ba. The problem caused the Windows Defender service to stop. For information on how to manually start a service, see the Help and Support center."

Why is this happening? How can I stop this?

I presume that Defender is still trying to startup. Go to RUN --> MSCONFIG --> STARTUP, and have a look. Is Defender there?

Windows Defender is out of Beta. I would un-install thru add/remove programs and go download the new version.

Are you btr94 the same person?

Anway, in Startup in MSconfig, look under the command column for the Defender directory, my version has a file name 'MSASCui' but that may be different to the betas. But I too would recommend installing the finished version.
