Vista - Security Center says that Windows Defender is turned off

I have been running fine for months now. Just yesterday the stupid icon
for my netowk connection gets x ed out red but i am still connected.
Also same with security center AVG 7.5 not recognized but still
running and also windows defender won't turn on. The fix doesn't work
for me either. The only thing i did last night that may havwe caused
something was updated my aim from 6.0 to 6.5 and i also deleted my
browsing history, cookies , and deleted temp internet files. None of
this should have caused this to happen. please helllpppp!!!!1

I have the same problem. I have not found the suggested fixes to be useful.

Specificially:
When Mohit Kapoor wrote > Please perform the following to resolve your

Open elevated command prompt and type cd\windows\system32\wbem press enter

Then type ren repository repository.old and press enter<
I tried to do that and was greeted with "Access Denied"

Then Mohit Kapoor wrote:command:

winmgmt /verifyrepository

If the system returns "WMI repository is not consistent", run this command:

winmgmt /salvagerepository

The first time you run this it will fail. (It will issue stop commands to
the services causing it to fail. It might take a couple minutes for the
services to shut down). Run the command again. You actually may have to
run it 3 times before it finally runs and completes on its own.

Reboot your system. <
But my WMI repository is consistent.

So, the security panel tells me that Windows Defender is off, but Windows
Defender tells me it is on.

I should add that I have have been using this computer for a week and did
not get the notice that Windows Defender was off until today.

Please advise.
Thank you!

What firewall, anti-virus application or security suite is installed? There
are some that cause problems which do not appear immediately.

also if you are running MS Onecare- it will turn off WD when running because
part of once care has WD built in it

I, too, am having the same issue. System was fine yesterday ... isn't today.
I have followed every step outlined in this thread ... even run the
/salvagerepository command MULTIPLE times with restarts ... no good ... I do
not have MS OneCare installed. I use Kapersky Anti-virus (Microsoft lists
this as one of the recommended products). Again, everything has been working
for months with no issues. Now, Windows security center shows Defender is off
and their is no anti-virus software installed. Defender itself shows it is
running, and Kapersky shows that it is running normally. Again, I have
followed every step suggested in this thread ... I'm still having problems.

Also, I tried to do a system restore and that failed as well with "The
writer experienced a transient error. If the backup process is retried, the
error may not reoccur (ox800452f3)".

Advice and additional help??

Have pretty much the same problem as Hornet's. Mohit Kapoor's method did not
work for me. I get a slightly different result from Petar's though and it
shows like this.......

C:\>winmgmt /verifyrepository
WMI repository verification failed
Error code: 0x80041003
Facility: WMI
Description: Access denied


C:\>winmgmt /salvagerepository
WMI repository verification failed
Error code: 0x80041003
Facility: WMI
Description: Access denied

I do not have anti-virus or xxCare One software installed. Previously the WD
was turned On.
