List installed Windows updates from the command line / DOS
It is easier than most would think to List installed Windows updates from the command line / DOS. This can come in handy if you have two identical machines and one is having an issue. You could save the output from both systems and use something like notepad++ or ultracompare to compare the contents of the files to determine if there is a specific update that might be causing something to break or fail.
The command to run from DOS is:
systeminfo | find “KB”
