19 19  In addition to the hints in that article, I found another trick: For me, the Server Cleanup Wizard was timing out when running the "Decline expired updates" action. I could fix this by running the `spDeclineExpiredUpdates` procedure from SQL Studio. I used "WUS Server" for the `adminName` parameter of this procedure. After that I ran the wizard again, and regenerated the indices. After doing this a few times, the wizard would finally complete without timing out. As always, make a backup of the `SUSDB` database before trying any of this.

66 +Strong cryptography for the .NET Framework has to be enabled in order for this to work, but even then I somehow couldn’t make this method work, so I resorted to opening the Microsoft Update Catalog in Internet Explorer and directly importing the updates from there (that method worked for me).
