WSUS clear declined updates

Question

I have lots of declined updates in my WSUS, I tried to run server cleanup wizard to clear it but failed.
Will wsus clear declined updates automatically? How to clear the declined updates manually?

Hi, @PeterRaban

Thank you for posting in Microsoft Q&A forum.

In my experience, WSUS will not clear the declined updates automatically, I always use below script to delete the declined updates:

 [reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration")  
$wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer();  
$declined=$wsus.GetUpdates() | Where {$_.IsDeclined -eq $true}  
$declined| ForEach-Object {$wsus.DeleteUpdate($_.Id.UpdateId.ToString()); Write-Host $_.Title removed }  

Here is the example in my WSUS:
