Hi, I need to change the time that virus notifications are retained. For a number of reasons I want the virus notifications to be saved (temporarily) for at most 1 day.

With PowerShell (as admin) I thought that this command would do it.

>Set-MpPreference -QuarantinePurgeItemsAfterDelay 1

but no, I get this error:

Set-MpPreference : Operation failed with the following error: 0x%1!x!
At line:1 char:2
+ Set-MpPreference -QuarantinePurgeItemsAfterDelay 1
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (MSFT_MpPreference:root\Microsoft\...FT_MpPreference) [Set-MpPreference],
CimException
+ FullyQualifiedErrorId : HRESULT 0xc0000142,Set-MpPreference

Can anyone help me with this change?

Version 23H2 (OS Build 22631.2792)

The syntax is correct. The command works for me using PowerShell 7.4.
Are you sure Defender isn't running? That is the only thing I can think of.

Hi OAT, I am a beginner with Powershell. Regarding the last part of your reply, all I have tried with Defender is to disable real time detection. Is this what you meant?

If you're not elevated, that's the exact error that's returned by PS.
