Windows defender error : Application failed to initialize: 0x80010005 and gadgets disappear

I have been getting this error since I installed Vista Home Premium two
months ago.
Sometimes this pop-up is seen (most times) but sometimes it is not seen.
I have applied all Defender updates from the Windows Update site.

Also, it appears that my Vista gadgets do not show when this Defender pop-up
is seen. Only when the Defender error is NOT seen at boot do I actually get
to see my gadgets (weird).

Any thoughts? I've already gone to the Defender forums with NO success.

I have the same problem

my vista windows defender worked fine until I updated my McAfee Security programs, now I get the same error: 0x800106ba

What did McAfee support say about this problem caused by their software?
Have you brought it to their attention?

I got it fixed early this morning. Appreciate
your assistance. Be blessed! :)-

Hey guys,

Sorry for the late reply but the answer for the defender issue is

1. Goto Services.msc
2. Choose Windows Defender
3. Choose Automatic
4. Start the service.

That's it.

It will resolve the issue

WHO NEEDS THIS CRAP???

WHY DON'T YOU GET "REAL" PROTETCION FROM PC TOOLS "SPYWARE DOCTOR"???
Do you think ANYTHING FREE is good? Nothign free is powerful, and so is
WinDefender - it works somehow but it;s lame, as much as Win Firewall is
lame comparing to real Norton Firewall.
