Yes but isolated registry backups make as much sense as a full backup of a modern Linux Desktop's /etc folder. Probably not much. The config's content depends a lot on the things installed and vice-versa, even more so on Windows (unless they changed something fundamentally since 7). At least on Linux and in particular Ubuntu (Desktop) installations I aim for as little manual configuration changes as possible anyways, so updates don't break things...
