Windows-11 How to clear Windows-defender: Quarantaine

Hi,

I work with Windows-11 and use Windows-Defender for protection

I see sometimes there are some items in the Quarantaine-box of Windows-Defender
My question is: Is it possible that i can delete these items out of the Quarantaine or are they deleted automatically after some time?

Thanks for all advice

Defender normally keeps quarantined files for 90 days, before automatically purging them.

You can choose to delete files by hand, or change the default retention policy in days from PowerShell (as Admin).

I use Defender UI, which allows for a much easier access to the different "bits and pieces" of Microsoft Defender.
It has an option to clear & repair protection history (see screenshot). And it gives you the possibility to remove the smart screen protection for newly downloaded apps (through a simple context menu entry).
