Export Installed Updates in Windows Server 2008 or 2008 R2

There is a quick command to export in a nice CSV format all installed updates in a Windows Server 2008 or 2008 R2 system:

1. Open a command prompt

2. Type: wmic qfe get /format:csv >C:\updates.csv

What is the benefit of it? This is a way to build a Changelog to track the changes performed in the system. Each Month or Scheduled update 'day' export the changes, so you can see the history of applied patches.
