I recently wanted to automate cleanup of my WSUS server. A lot of posts around the web advocate using strange PowerShell scripts that make .NET calls to work with WSUS or even use third-party applications to do so. That information all seems outdated. On server 2012 R2 you only need Invoke-WsusServerCleanup.

Recently we purchased Ninite Pro for our organization and have implemented silent application updating via a scheduled task with PowerShell. This process uses a cache on our LAN to store updates and speed the whole process along. After some thinking I decided I wanted to get this working off-site so that when students take their laptops home over the summer, they can continue to receive updates.

For when you find that you just need to remove all of the drivers from a captured image, or only those of certain makes. PowerShell makes it easy to script this removal so you aren't manually typing a ton of dism commands. I found myself needing to purge some problematic Intel drivers from an image in order to get USB working on some of our older machines. I found that it is possible to remove all drivers from a mounted Windows image and then commit the changes back to the captured WIM completely in PowerShell. Read on if you need the skinny.
