This post showed students and new users the steps to manually clear Windows Security Protection history events on-demand.
The Protection history page in the Windows Security app is where you can view actions that Microsoft Defender Antivirus has taken, including Potentially Unwanted Apps removed or critical services turned off.
By default, Protection history only retains events for two weeks, after which they’ll disappear from this page.
However, instead of waiting for event logs to clear, you can manually clear them before they’re automatically removed.
Below is how to do that in Windows 11.
