Windows Task Scheduler Doesn't Run VBScript

问题

I am trying to automate a VBScript by using Windows Task Scheduler. However, I tried to use cscript.exe + "C:\...\script.vbs" but it didn't run. I also tried to directly run the same command in CMD (cscript.exe "C:\...\script.vbs") and it worked.

What might be the problem?

EDIT :

I just tried to switch the setting to "Run only when user is logged on" from "Run whether user is logged on or not" and it worked. I am wondering if there is a way to make my task scheduled run even when the user is logged off.

After hours of research, one of Blake Morrison (from Microsoft)'s blogs came up; it mentioned that

If running a .vbs / .ps1 script, try launching it from a .cmd / .bat script

see Help! My Scheduled Task does not run…

That blog also explains a lot of rules/tips when using Task Scheduler.

So please create a .cmd/.bat file that calls for your VBScript. For example: cscript.exe YourScript.vbs would be in your .cmd/.bat script.

Write a batch file like this:

echo "Started!" > c:\foldergoeshere\log.txt
cscript.exe "C:\...\script.vbs" > c:\foldergoeshere\log.txt
echo "Stopped!" > c:\foldergoeshere\log.txt

Then schedule the batch file instead of the vbs. That will allow you to see what is happening that is preventing it from running. Any error that you would have seen executing in the console (CMD), will be instead output to that log file between "Started!" and "Stopped!"

What's the hassle all about? I don't use .cmd/.bat and script works! (Windows7 here)
My VBS script (as a scheduled task) runs well on any scenario of these 4:

cscript and option "Run only when user is logged on"
cscript and option "Run whether user is logged on or not"
wscript and option "Run only when user is logged on"
wscript and option "Run whether user is logged on or not"

It's only that on the 1st scenario I encounter the black command window flashing on my screen.

Action settings:

My script, which simply creates a file:

Set objFSO = CreateObject("Scripting.FileSystemObject")
filename = "C:\Temp\" & Hour(Time) & Minute(Time) & Second(Time)
Set objFile = objFSO.CreateTextFile(filename)

The .vbs file is running invisibly, which is a consequence of running it with the 'logged on or not' option.

You will not be allowed to interfere with a user using the computer, which means you will be able to help yourself, but not others.

Please read the following text from the Task Scheduler Help menu:

Task Security Context

You can specify that a task should run even if the account under which the task is scheduled to run is not logged on when the task is triggered.

To do this, select the radio button labeled Run whether user is logged on or not.

If this radio button is selected, tasks will not run interactively.

To make a task run interactively, select the Run only when user is logged on radio button.

Have experienced more than once that a VBScript running as planned task worked fine for months and years but suddenly would not work any more despite nothing was changed. Have tried to reactive the task using all the recipes given here and elsewhere, but no success. My workaround was to create a new planned task with all settings copied from the original one.
