I encountered [this comment][1] while browsing questions on Super User:

> "**Remember to always be careful with the registry!**": Such a notice should be added, because newbies can mess up! Also, instructions for a registry backup are useful, in case something goes wrong with the .regs. – [Έρικ Κωνσταντόπουλος][2]

The [answer's timeline][3] indicates that the answer was edited to add a warning in response to the comment.

Should we add a warning to back up the registry (like the one added to said answer) to every answer that involves editing the registry?
