Cannot start Task Scheduler (Error 13: The data is invalid)

Question

As the title of the post says, I am unable to start Task Scheduler through Services. When I try, I get the following error:

"Windows could not start the Task Scheduler service on Local Computer. Error 13: The data is invalid."

I'm not sure what's causing this error or how I could go about fixing it. Does anyone know what to do?

Sorry if this is in the wrong topic. I'm not really sure what category this issue would fall under.

Hi Max,

The service configuration looks good.

Please see if a repair installation fixes the Task Scheduler error.

1. Download Windows 10 Media Creation Tool (MCT) from this link:

2. Run MCT and accept the license agreement.
3. Click "Upgrade this PC now". This starts the repair installation.

Let me know where to go from here.

Answer 3

Hi Max, This is Ramesh.

Let's check the scheduler service's configuration. Please open a Command Prompt window and maximize it.

Run this command:

reg query "HKLM\SYSTEM\CurrentControlSet\Services\Schedule" /s

Press Enter.

Copy the output and post it here.
