RE: Security Center says that Windows Defender is turned off

[Guest wayne_s]

My Windows started to have similar problem yesterday. The Windows Security

Center showed Windows Defender is out of date. but after mannual update, I

received a message: "There are no new definitions available to download for

Windows." In Windows Defender, it states Real-time protection is on and

Definition version is 1.43.73.0 created on 9/4/2008.

I have tried Mohit Kapoor's solution, but have some problem as Grich had.

After I run winmgmt/verifyrepository, system responded "WMI repository is

consistent".
