```

When returning to the Administrator account, even the e shortcut in the quick launch bar is gone, leaving only the shortcut on the desktop.

Possible incorrect statements:
sc config schedule start= auto>nul 2>nul
at /delete /yes

I don't know what you're up to. What's your intention?

This is a batch script to switch to the SYSTEM login account:
It shows that after executing the batch script, it hides itself until the next minute to perform the switch action!

But there are some BUGs!
It shows that the first run is normal, that is, switching from Administrator to SYSTEM! After logging out of SYSTEM and returning to Administrator, running it again stays on an empty desktop (nothing on the desktop)

Now it is determined that the line with at /delete /yes is the error statement. Commenting out this line is normal, but I don't want the completed task to remain in the task scheduler after running this batch script.

How to handle it?

Does the /delete /yes command have permission? This VBS is very simple

It was also run in Administrator the second time, so the permissions should be okay. Anyway, I can't explain it clearly, you can test the code above!

There is no such bug as you mentioned here

Wait a minute, I'll write a VBS for you~~~~

```vb
Set WsShell = CreateObject("WScript.Shell")
Set objWMI = Getobject("Winmgmts:")
Set Process=objWMI.ExecQuery("Select * From Win32_Process Where Name='Explorer.exe'")
For Each objProcess In Process
intReturn = objProcess.Terminate(1)
Next
SithTime = FormatDateTime (DateAdd("s",60,Time) ,0)
WsShell.Run ("%Comspec% /c " & Chr(34) & "sc config Schedule start= auto&net start Schedule" & Chr(34)),vbHide
Wscript.sleep 2000
WsShell.Run ("%Comspec% /c " & Chr(34) & "at " & SithTime & " /interactive %SystemRoot%\Explorer.exe" & Chr(34)),vbHide
Wscript.sleep 120000
WsShell.Run ("%Comspec% /c " & Chr(34) & "at /delete /yes" & Chr(34)),vbHide
```

1. It takes too long to wait for the blank desktop. Can the action be executed only 3 seconds before the run switch?
2. Outdated tasks remain in the task plan.
3. Just like my batch script, the e shortcut in the quick launch bar is gone, leaving only a shortcut on the desktop!
4. The first function I achieved with my batch, the others are equivalent to my batch and have the same problem!

Hope to be corrected!

Summary: I still prefer the batch method because I am not familiar with VBS!

Wscript.sleep 120000
Subtract 1 minute from 2 minutes for the waiting of at execution, that is, waiting for 1 minute. Maybe it's a bit long, but it's also necessary. (For the first login, with a slightly worse configuration, it might not have logged in to the desktop in 1 minute)

SithTime = FormatDateTime (DateAdd("s",60,Time) ,0)
This is to set the next minute (60 seconds) of the current time
Wscript.sleep 1000 = 1 second

fastslz misunderstood the question in the top post?!
1. Not converted or rewritten to VBS
2. Residual tasks not resolved!
3. e shortcut not resolved!
4. Newly discovered that there is also a deadlock phenomenon, manifested as no response when clicking desktop icons with the mouse, and it is normal only after logging out and logging in through the task manager!

The reason you don't have this bug is that you haven't dealt with the remaining outdated tasks. If I comment out "at /delete /yes" in my batch file, there is no (blank desktop) error, but a new problem will occur (remaining outdated tasks)

Let's put aside other things like the shortcut of e and the unresponsive phenomenon!

1. Batch processing to calculate the next minute is inaccurate (even if made very accurate, the code is more complicated), VBS is accurate to the second
2. Residual tasks are okay
3. The e shortcut is also okay
4. No freezes either
5. In short~It depends on the personal system situation
