Windows 10: How to backup and restore the Windows 11 registry?

I'm new to Windows 11 I'm running 23H2, 22631.3447. I would like to install a piece of software namely, Winaero Tweaker that will likely make changes to the Windows 11 registry. I would like to backup the registry in case problems arise. How do I perform a one-time backup of the registry? And how can I restore that backup in case problems arise? I found a tutorial on how to enable automatic backup of the system registry upon restart, but how do I manually perform a one-time backup of the registry?

How to backup and restore registry using only win10 iso command prompt

In a link it suggested several registry troubleshooting steps for a Windows with black screen.

For Windows 10 1909 how do you backup and restore one registry change using a windows 10 iso command prompt?

If more than one registry entry is modified how do you backup and restore a second change?

In addition to modifying one or two commands how do you backup and restore the whole registry when the only access is via a windows 10 iso command prompt?

 

How to backup and restore registry using only win10 iso command prompt

The only access post windows upgrade is Windows RE using a windows 10 iso.

Registry steps may be needed that require deletion of the registry entries.

Aren't there two methods for backup: a single change and the whole registry?
I've never done either and need specific steps using Windows RE command prompt.
Also I've never restored a registry backup.
How do you restore a single backup using Windows RE command prompt?
And how do you restore the whole backup?

Again I've never done any significant changes in the registry and need specific steps using only the Windows 10 iso.

 

How to restore registry values?

Hello,

Thank you for posting your query on Microsoft Community.

You can perform system restore and check if it helps:

Perform System restore.

I suggest you to perform system restore and select a date prior to the changes which was done with the registry values and check if the issue gets fixed.

To perform System restore:

• Press Windows key + X, select
  System.
• In the left pane, click on System Protection.
• Select the option to system restore
  > next. It will show all restore points already created.
• Select the date prior to the date on which you have made the registry changes.
