Problema
Aprendo la console WSUS ci sono degli update che non si possono approvare perchè sono SuperSeded da un altro piu' recente.
Ma non si riescono nemmeno a declinare e continuano a bloccarsi.

Risoluzione
Si puo' fare anche con AjTek WSUS Cleaner, tuttavia ho messo uno script Powershell in C:DownloadsDecline-SupersededUpdates.ps1 sul server WSUS che declina gli update SuperSeded.

To do a test run against WSUS Server without SSL

./Decline-SupersededUpdates.ps1 -UpdateServer IPAM -Port 8530 -SkipDecline

To do a test run against WSUS Server using SSL

./Decline-SupersededUpdates.ps1 -UpdateServer IPAM -UseSSL -Port 8531 -SkipDecline

To decline all superseded updates on the WSUS Server using SSL

./Decline-SupersededUpdates.ps1 -UpdateServer IPAM -UseSSL -Port 8531

To decline only Last Level superseded updates on the WSUS Server using SSL

./Decline-SupersededUpdates.ps1 -UpdateServer IPAM -UseSSL -Port 8531 -DeclineLastLevelOnly

To decline all superseded updates on the WSUS Server using SSL but keep superseded updates that were published within the last two months (60 days)

./Decline-SupersededUpdates.ps1 -UpdateServer IPAM -UseSSL -Port 8531 -ExclusionPeriod 60
