Alienware 17 R3 setup question.

Will windows 10 updates overwrite the custom drivers??  I will install Macrium for drive imaging in hopes of having an easy way to revert if the system gets hosed.

What are the best setup practices, and will Win10 begin updating before I can install Macrium?

It seems that Win 10 updates can mess up these systems and that Dell doesn't have an easy way back to a working config.

A best practices walkthrough might avoid a lot of the problems new owners seem to be having.
