Windows 10: Scheduled Defender Definition Updates Not Completing After AU Solved

    Scheduled Defender Definition Updates Not Completing After AU


    Going back to Windows 8 I have created a task to manually update Windows Defender definitions on a schedule. This is fairly straightforward as detailed here Auto update Windows Defender and here http://www.thewindowsclub.com/update...dates-disabled.

    Today I noticed the computer that has updated to AU is not completing the task. I get "The system cannot find the file specified. (0x80070002)".

    The created task and the included argument is the same on all my computers. "“C:\Program Files\Windows Defender\MpCmdRun.exe” -SignatureUpdate​".

    My other computers, which do not have AU, complete the task without error. I am fairly certain the one with AU also completed it prior to the update. AFAICT the file location is named correct and is the same after the AU so why can it not find the file specified?

    It appears Defender is updating definitions on its own (not frequent enough which is why I schedule the definition updates) and I can update them manually through the program so the function is working.

    I have resolved this. The Action entered has to be modified to:

    "%ProgramFiles%\Windows Defender\MpCmdRun.exe" -SignatureUpdate
