Exchange-Genie

If you are like me you copy the installation bits to the local machine or run them from a network share however you can install Exchange rollups but dropping them into the updates directory.

Just place the rollup in this directory and launch setup, the installation will also install the rollup saving time on the installation.

You can also perform that same action from the command line

Use the /UpdatesDir parameter to specify the directory from which updates will be installed. If the updates folder contains spaces, you must enclose it in quotation marks. Files in the Updates directory must be either an Updates.exe file, or one or more *.msp files. Setup will install the updates before installing the Exchange server roles specified.
