How to run a batch , .bat, flle as administrator

[blockie]

I run a batch file from the Windows scheduler and get an error 5, 'access denied'. If i run the batch file as administrator I have access and everything is OK except I must answer the UAC popup. The question is "How can I run the batch file from the scheduler with admin privileges and NOT have to answer the UAC question"?

Hello William,

You might see if using Option Five in the tutorial below on the .bat file to always have it "Run as administrator" may work when running it with Task Scheduler, but you'll still get the UAC prompt.

​

To not get the UAC prompt, you might see if using the method in the tutorial below to run the .bat set as above may help.

Hope this helps.

Try setting the "Run with highest privileges" checkbox on the general tab of the scheduled tasks properties.

Brink,
I tried option 5 and the RUN AS ADMIN is greyed out and I cannot access it to put a check mark in it. I am the only user of this computer and do have admin privilege.

How does the elevated shortcut from the second tutorial run for you using the .bat as is when creating it?

How does the elevated shortcut from the second tutorial run for you using the .bat as is when creating it?

This is what I am trying to do.
1. Delete excess Macrium image backup files from my external HDD. The oldest ones first. I do this at night when the computer is on but unattended. The files I use to do this are contained in folder MyScripts on the desktop.see attached (capture.jpg)
2. The script in delmacimage.bat file is
"DELOLDER cd/D D:\macrium\images\*.mrimg /Keep:6"
The bat file does, in fact ,deletes the required number of files in the intended folder. When I put it in the schedular is where I get in trouble.
3. Security level is all permissions for user "everyone"

Did you check "Run with highest privileges"?

 

[blockie]

Yes. see attached (3 files)
The arguments for the Action tab are:
/c start "DELMACIMAGE.bat" "C:\Users\William\Desktop\MyScripts\"DELMACIMAGE.BAT "

The shortcut for this does not work. I don't get any error msg's but it does not delete any files either. The only thing that happens is the desktop "blinks" when I use the shortcut. Blink means it looks like a cmd window opens for a fraction of a second

DELMACIMAGE.BAT does delete the excess files. The cmd window opens and the action (deletion of files) can be seen.
The new shortcut just "blinks".

Did you start the Task Scheduler using the "Run as administrator" option (in the context menu)?

​

Did the Task Scheduler ask for your Administrator password when you were finalising the task?

Does it make any difference if you change the user from "William" to "Administrator"?

1. I did as the tutorial said.
2. Yes, I was asked for the password and I put it in.
3. William is an Administrater. But I will change it tomorrow. I also have a everyone user with full privilege.

 

[Layback Bear]

Just a thought.
Do you have a option for Systems to have full permission.

 

[lehnerus2000]

Administrators Group != Administrator

Human users (i.e. you and me) don't get "full administrator power", even though Windows says we are in the Administrators Group.

The built-in Administrator (i.e. Username: "Administrator") has more power.

On my PC, I'm an administrator and I have received the "You don't have permission to do this. Contact the Administrator" message, when I have been attempting to perform operations.
Though the last time was so long ago that I can't remember what I was trying to do.

Try changing the user to SYSTEM and see if the task works the way you want.

Thanks to everyone, But on further investigation of Macrium Reflect, I found that I could put an option in the vmx file that deleted old backups automatically. So this thread becomes not solved but not needed.

 

[bender123]

Sorry to resurrect this old thread, but I am dealing with the exact same problem. I have followed each item in the previous posts, but no luck.

I do have one more piece of information, though. When I remove the the argument to run the batch file in Task Scheduler the CMD window will open as Administrator. When I add the argument back it will not open as Administrator.

Can anyone provide insight into this problem?

Much Thanks.

Try with this test batch file. It only prints 2 things, if it's running as administrator or not, and the parameters.

@ECHO OFF
AT > NUL
IF %ERRORLEVEL% EQU 0 (
    ECHO Administrator=YES
) ELSE (
    ECHO Administrator=NO
)
set PARAMS=
SET /A COUNT=0
:CHECKPARAMS
SET /A COUNT+=1
IF [%1]==[] GOTO CONT
IF [%COUNT%]==[1] (
    set PARAMS=%1
) ELSE (
    set PARAMS=%PARAMS% %1
) 
SHIFT
GOTO CHECKPARAMS
:CONT
echo Parameters: %PARAMS%
echo.
pause

When I try to run it from Task Scheduler as admin(Run with highest privileges) and arguments: param1 param2

Administrator=YES Parameters: param1 param2 Press any key to continue . . .

Also test if the option "Run only when user is logged on" makes a difference.

I made a a batch file.
I called it test.bat when I saved it.
Then I create a shortcut of the real test.bat so I have a test.bat - Shortcut
I then Right-click on the test.bat - Shortcut and then I choose properties and then I select advanced in the properties section.
When you have done that there will be a new box you can mark as "Run as administrator".

Try that for starters.

 

[bender123]

Mikkel, thanks for the reply. I tried that, but the batch file is to be run unattended so I will not be around to accept the UAC message.


Tookeri,
I can't modify the batch file. Also it looks like it requires user interaction, which needs to be avoided.


Thanks

@bender123, I meant you could add a new scheduled task with this test file to see if that works. It works for me so if it works for you too then it's probably an issue with your other batch file or the properties of its scheduled task. This will verify if it's possible from a scheduled task to start a batch file with parameters as administrator.

It doesn't require interaction. The "pause" is there only so you can verify the output, but you could just close the window. It's just a one-time test, nothing you should keep.
The troubleshooting for your issue has to start somewhere and this was my idea for starting point.

 

[bender123]

Thanks, Tookeri!

I misunderstood the purpose of your script. I do see a difference in the output when I select/deselect "Run with highest privileges".

I just realized when my Scheduled Task is run it uses taskeng.exe and not cmd.exe. Maybe there is a difference in the way these applications display the privileges?
