how can I programmatically in .net backup or restore a regedit node?

Question

I store (ie. persist) my app's settings in regedit, and want to be able to save them in a file, and restore later.

How can I store everything in a specific regedit node (little yellow folder on the left)?

Regedit is a tool to access the registry. So you're not storing things in regedit, you're storing them in the registry. That might help search for answers. From a quick look https://www.c-sharpcorner.com/UploadFile/f9f215/windows-registry/ seems to answer your question. — Ben, Jan 21 '19 at 22:37
The, possibly, simplest way is using a predefined utility, `reg.exe`. You can start it with `Process.Start()`. To see what it does, open a `cmd.exe` prompt and enter `REG /?`. You can call it from your app without a visible console window, setting up the `ProcessStartInfo` with `.CreateNoWindow = true.` — Jimi, Jan 21 '19 at 22:51

There are several ways to do this. You can use regedit.exe to export it to a reg file for backup and use the file for restoring purpose.

Example to export subkeys to a reg file

regedit.exe /e c:\temp\out.reg "HKEY_CURRENT_USER\Software\Microsoft\InputPersonalization"

Or use P/Invoke to call RegSaveKey and RegRestoreKey to do this

Or use .Net Framework Microsoft.Win32.Registry to read and write values to a different file.
