I have an application that depends on the .NET 5 runtime being on the server. One day it started failing with strange messages. Turns out the .NET runtime was no longer there. Ok, thats strange. So I started looking through windows updates etc. Not sure where to look.
What Ive done so far is look through the Windows app log with the filter on MSIInstaller and I found a few hits on or before the problems started. Given a specific KB# how can one find the contents of what was being done for this update?
