Nothing much has been changed in the Exchange 2010 SP1 clean install compared to the beta version. The option to automatically install Exchange pre-requisites as part of the setup is still there (same as beta, check my previous article).

Automatic pre-req install

The option to configure split permission model comes up, same as the beta version. Check my previous article.

Split permission

The only change is a nice warning when you install 2010 SP1 on a domain controller. You are warned that the exchange server on a DC will elevate the permissions for “Exchange Trusted Subsystem” to domain administrators.

2010 SP1 Warning

Exchange on a single box (with DC role) is fully supported by Microsoft and hence you can safely ignore the warning if you have a similar setup in production.
