Windows Defender Scheduled Scan - Set Up in Windows 8

    This didn't work for me. After setting this up and waiting until the scheduled time, the Last Run Result shows (0x2) and there was no indication that a scheduled scan was running (CPU usage is idle in Task Manager, Action Center shows nothing, etc.).

    I then attempted to execute the scheduled task manually, but after running for a minute or two (which is way too short for a full scan to have completed) I get the same (0x2) result.

    Any ideas?

    I don't see any problems in your screenshots.

    What time do you have automatic maintenance set to run? By default, it's 2AM as well, and could be interfering with and cancelling this WD task giving you the 0x2.

    Automatic Maintenance - Change Maintenance Settings in Windows 8


    Since the WD task to run a full scan will take a while to finish, it would be best to have it scheduled to run after automatic maintenance, or way before automatic maintenance so that the full scan will have time to finish first. The time for automatic maintenance varies per system, but I would allow it about 2-3 hours to be safe. A WD full scan just varies to much per system to be able to give a time frame on it though.

    This is strange... Automatic Maintenance says it's scheduled to run at 3:00 AM, yet the last run time according to Action Center is at 1/5/2014 2:19 AM.

    Either way, I'll try changing the Windows Defender scan time to midnight for now. I'll let you know if it helps or not.

    That can happen if automatic maintenance failed to run at the scheduled time, and throws the time to run the task off a bit.

    Of course the computer will need to be turned on and running, or asleep and set to wake the computer, to be able to run the WD task.

    Does it run when you manually run the task yet?

    Nope. The scheduled task is completely broken. The only way I can start a scan is by going into the Windows Defender UI and pressing the Scan Now button.

    [Edit] Spoke too soon - the moment I plugged in the AC adapter, the scheduled scan started running. Could it be that Windows Defender itself has some kind of built-in requirement for AC power that overrides whatever I set on the "Conditions" tab?

    Interesting. Having the top two boxes unchecked under Power in your screenshot below should allow it to be able to run under battery power instead of just while plugged in.
