Exchange Server 2013 - Preview Prerequisite Script – Major Update

After noticing the lack of a script to help install the Exchange Server 2013 Preview prerequisites and creating a basic one for Windows 2008 R2 SP1 OS installs, I’ve taken a few days to make some major updates. The script now checks for either Windows Server 2008 R2 SP1 or Windows Server 2012 Preview for base OS prerequisites. When the script is run an OS specific menu is displayed, one for 2008 or one for 2012. Once that menu is displayed you are able to install all the prerequisites for either the CAS role or the Mailbox role, run Windows Update, check the prerequisites for each role as well as install each prerequisite individually.
Change Log:

• Addition of Windows Server 2012 prerequisites
• Prerequisite checking for Windows Server 2008 R2 SP1 and Windows Server 2012
• Cleanup of excess code and reformat of certain code bits

Over the weekend I will be working on a detailed explaination of the script in the hopes of educating Exchange admins on the power of PowerShell for more than just management of Exchange.

Download the script from here. Please leave feedback or ask questions if you want.
