Tip of the Day: Is a hotfix installed?

Today’s Tip…

Command1:: syteminfo | findstr KBXXXXXX. This command would show you if the fix is installed or not, on the system you are running the command. It is important to note that in the command KB has to be typed in uppercase followed the fix number without any space.

Suppose you would like to verify if the KB is installed on any other system. You can specify the name of the system with the /s switch, like in the example below. This is very useful to check the updates from a single node about the status of the updates for all nodes. Just keep changing the names of the nodes.

Command2:: syteminfo /s <SYSTEMNAME> | findstr KBXXXXXX
