whenever i try to start windows defender a box popup saying that application

failed to initialize, ox80070002.need any help that i can get please

i'm running windows vista.

I've noticed that this update for Vista actually re-creates/re-modifies all

the files under C:\Program Files\Windows Defender, which are necessary to

run Defender. (The update also resets files under

C:\ProgramData\Microsoft\Windows Defender\Definition Updates\Default). In

other words, it appears to essentially re-install Defender for Vista:

Too, the update also creates two new folders in C:\Windows\winsxs, which

would be used by the System File Checker utility.

 

I would try downloading and installing the update, first. If Defender still

doesn't work, try the System File Checker, by right-clicking on Command

Prompt (Start Menu\Programs\Accessories), and choosing Run as Administrator.

At the prompt, type the following:

 

sfc /scannow

 

Press enter on your keyboard. The scan may take awhile.
