How Dangerous is Editing the Windows Registry?

[Tom.G]

TL;DR Summary: I've seen, heard of people editing the registry . Some , though, warn of the dangers of incorrect editing. Who should we believe?

Hi, curious as to do something I want to do on My Win10 PC, which requires editing the registry.

You may get somewhat better answers, and perhaps even suggestions, if you clarify what that "something" is that you want to try.

Sure, you can back it up. The better question, though, is whether you can restore it. If the corruption is a little bad, no problem. If it's very bad, and Windows won't start, how do you plan to restore it?

If you have a system image backup and repair disc made, you can always restore after trying a registry change.
