You're welcome and thank you for testing this.
don't worry about the rep - thought appreciated.
As we discussed, here is how i have the task setup so there is no CMD window.
Let me know if there are any questions/issues.
I have my Scheduled MSE definition update setup to NOT use a BAT file.
Task Scheduler runs MpCmdRun.exe directly, rather than via a BAT file.
The difference is this way you won't see the CMD window every time the Task runs.
Some people prefer seeing the BAT CMD window, I don't.
It's a personal choice...
Either way you can check if the update process works by looking in Windows Update History.
For anyone that does not want to see the BAT file CMD window, here is how I have Task Scheduler setup for MSE V4
I set up the task running Task Scheduler with my ADMIN account (run as administrator).
I use the PC logged in with my STANDARD account. Task summary/highlights:
Task properties (General tab):
Author: <my ADMIN> account
"Run whether user is logged on or not" is selected
"Run with highest privileges" is checked
On a scheduleAction:
Recur every 1 days
Repeat task every 4 hours for a duration of 1 day (4 hours is my personal choice...)
Program/Script: "C:\Program Files\Microsoft Security Client\MpCmdRun.exe"
Add Arguments (optional): -SignatureUpdate
