It turns out I was doing this all wrong for months. For the longest time, I’ve been checking my SQL Server instances to see what needs patching with Test-DbaBuild from the dbatools PowerShell module. But the result was always the same - it never returned a Service Pack or Cumulative Update target. I glossed over it because I knew what the right answer was already, but recently I decided that wasn’t good enough. We need a reliable report to give to other people.
