Every now and then you need to check if your servers or client computers have pending updates. You can generate a simple list of this with Powershell. I have created a script for this on my Github named ListPendingWindowsUpdates.ps1. Here is a quick breakdown of the script, feel free to use and modify it anyway you like. Please comment below what you ended up doing with it.
We always need to declare the functions of the Powershell script first but I will dig into the only function of this script below and start with the locally executed code. This script have one locally executed part and then a function that is executed on each and every server/client it lists. For this to work you need to run the script with domain admin rights. Both to access the Active Directory and to remote execute the code on each server/client.
