SuppressStateChanges value for Exch2010 Prep

I ran MS Exchange Pre-Deployment Analyzer (ExPDA) on my Windows 7, and got this warning message below.

Googled and found the the solution below,

1. Open Registry Editor.
2. Locate HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RESvc\Parameters.
3. Right-click Parameters and select New | DWORD value. Name the new DWORD value SuppressStateChanges.
4. Double-click SuppressStateChanges.
5. In the Value data field, enter 1.
6. Close Registry Editor and then restart the Simple Mail Transfer Protocol (SMTP) service, the Microsoft Exchange Routing Engine service, and the Microsoft Exchange MTA Stacks services for the change to take effect. (Thanks for this good article.)
