First this is my first post in this forum.have heard a lot about this community :)

 

 

 

Hello

 

I am using windows 8 in my office.I have disabled windows updates and because of that defeneder dosent updates itself.but sometimes it does.

 

i searched and found i can create a task in task scheduler using this option

 

MpCmdRun.exe -SignatureUpdate -MMPC

 

 

But the problem in this is that it popups the command prompt when it starts.I want that it runs in hidden so that users in my office dosent sees whats happening.

 

 

how can i do it so?

 

 

thanks

 

 

 

Ankit

============
Another option might be to try piping to NUL (or NULL, don't remember which it is):

MpCmdRun.exe -SignatureUpdate -MMPC > NUL

 

or

 

MpCmdRun.exe -SignatureUpdate -MMPC > NULL

But like I said, I don't use Defender, so this is a "best guess".

Best of luck.
