Situatie
If you have a .BAT file and you’re trying to get it to run automatically using Task Scheduler in Windows, you might have run into the issue where it simply doesn’t run unless you manually run the task. I created a batch file that deletes everything inside a temp folder whenever the computer starts up. I created a basic task in Task Scheduler and hoped for the best. Unfortunately, nothing happened when my computer booted up. After a lot of trial and error, I figured out how to get the script to run.

The first step to fixing this issue is ensuring that the account you are using to run the script in Task Scheduler has Full Control permissions on the folder containing the script, the script itself, and any folders/files that the script touches when it runs.
For example, I created the following batch script below:
set folder="C:\test"
cd /d %folder%
for /F "delims=" %%i in ('dir /b') do (rmdir "%%i" /s/q || del "%%i" /s/q)
I saved the .BAT file to my Documents folder. The path is C:\Users\username\Documents. I went to C:\Users\username, right-clicked on the Documents folder, and clicked on Properties. Then I clicked on the Security tab.
As you can see, the user account Aseem has been explicitly added and given the Full Control permission. Now you have to do the same thing for the folder that contains the script and for the script itself. Don’t just assume that if you give permissions to the folder containing the script, you’re good to go, because you’re not. Lastly, set permissions on any files and folders that the script will interact with.
In my case, I had to go to C:\test, right-click on that folder and add my user account there with Full Control permissions. It’s kind of annoying that you have to do this, but it’s the only way to get the script to run.
Step 2: Check Task Scheduler Settings
Now let’s go to Task Scheduler and change the appropriate settings there. Open Task Scheduler and find your task under the Active Tasks section. They should be listed out in alphabetical order.
Double-click on it and it’ll open the task by itself in the same window. In order to edit the task, you’ll have to right-click on it and choose Properties.
There are several tabs and a couple of things have to checked and changed here. Firstly, on the General tab, you need to check the user account that is being used to run the task. In my case, it’s the Aseem account, which I had given permissions to earlier on the file system and which is part of the Administrators group on the computer.
Next, you have to choose the Run whether user is logged on or not option and choose Windows Vista, Windows Server 2008 in the Configure for box.
On the Actions tab, you have to select the script, click on Edit and then add in the path to the folder containing the script in the Start in (optional) box. This may seem unnecessary, but it’s not. In my case, I put in C:\Users\Aseem\Documents\ in the box.
Now click on OK to save the settings. When you do this, a dialog may appear where you have to enter the password for the user account that will run the task. This brings up another requirement. You can’t use an account that doesn’t have a password. The user account has to have a password in order for the task to run.
Lastly, you should run the task manually once in Task Scheduler to make sure it runs. If it runs fine manually after you changed all the settings, then it should run when it’s supposed to be triggered. In my case, it was supposed to happen on startup and after I made the changes, everything worked fine.
Another item to note is if your script accesses resources on a network share. If your script is using letters to access the network, it may not run. For example, instead of using F:\data\, you should use \\machinename\share_name\data\ in the script.
