Hello,

Just a question regarding restoring DC from backups if Schema Breaks when preparing and executing commands to prepare Schema for exchange server 2010. Any assistance would be appreciated.

Can I just restore the regestry from mylatest DC backups? What are the procedures?

If something were to go wrong,a forest recovery would be required. Exchange schema updates have been throughly tested however and applied to many an org.

However, apply in a lab first if concerned.

Do it the recommended way.
Disable outbound replication on your schema master (I think it is repadmin /options +DISABLE_OUTBOUND_REPL) Extend the Schema and check that eveything is happy after. If it is happy: Enable outbound replication and continue. (I think it is repadmin /options -DISABLE_OUTBOUND_REPL) If it isn't happy: Power of the schema master, format it, do a metadata cleanup in AD, seize the Schema Master Role to another DC, reinstall the box you just flattened.

If I was applying some 3rd party schema updates I may do that. Otherwise, it's probably not something the average installation needs to be concerned about.

Agreed. I've never had a MS schema update "go wrong", but wanted to give him the option. :)
