How to back up and restore registry settings in Windows 10

Whenever you make changes to the Windows registry, it is recommended that you make a backup first. You can back up your entire registry easily enough and then restore it if something goes wrong.

If you only edit one or two registry values ​​and plan to make other registry changes later, one backup will not be enough.

It is a good idea to make new backups every time you edit the Registry, since you can make as many copies as you need. It is much easier to back up individual branches, especially if you frequently edit the registry. You can back up and restore registry settings from a backup. Here’s how.

Create a backup copy of a registry key

Open the Windows Registry and navigate to the branch you want to back up. right-click and select “Export” from the context menu. Save the registry key in a location where you cannot accidentally delete it. If the select branch has subkeys, they will also be saved.

With Windows 10, Microsoft has added the ability to quickly open a Registry key directly, without browsing the entire its tree.

Switch between HKCU and HKLM in Registry Editor

In the Windows 10 operating system, Microsoft added the ability to quickly navigate between similar registry keys of the HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER branches.

For example, the SYSTEM subkey exists in the following branches:

  • HKEY_LOCAL_MACHINE\SYSTEM
  • as well as HKEY_LOCAL_MACHINE\SYSTEM

To switch between them, follow these steps.

  1. Open the registry editor.
  2. Go to the required registry key, for example, to the subkey: SYSTEM
  3. Assuming that you have finished working with HKCU and want to continue with its corresponding branch under HKEY_LOCAL_MACHINE, right-click on the SYSTEM subkey and select the Go to HKEY_LOCAL_MACHINE command from the context menu.Switch Between Hkcu And Hklm
  4. And vice versa – from HKEY_LOCAL_MACHINE \ you can switch to HKEY_CURRENT_USER \ SYSTEM instantly.

Remember that this trick only works with keys that have similar paths under HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE.
