Windows Defender quarantined files

Question

Hi @all ,

when will the quarantined files been deleted automatically?

I know the Registry Keys:
LocalSettingOverridePurgeItemsAfterDelay 1
PurgeItemsAfterDelay 30

As far as i understood all quarantined which are older then 30 days should be deleted.
But when is Windows Defender running the cleanup?

Answer 1

Hi @Florian Zepter ,

The Windows Defender cleanup is a scheduled task called Windows Defender Cleanup which can be found in the Task Scheduler (Task Scheduler Library\Microsoft\Windows\Windows Defender), I believe this task is only run if there are any items in the quarantine.

If the registry key PurgeItemsAfterDelay has the value of 30, it means that Windows Defender will purge the quarantined items after 30 days.

Answer 2

Hi Leon,
thanks for your answer.
the problem I am seeing is that the cleanup is not triggered automatically and the quarantined fails are not cleaned up.
