I found this the other day…..
This is not exactly what you are after, but well worth knowing if you tinker with your registry to remove obsolete bits and make a mistake and want to restore it.
How to make a backup of the Windows registry
Situation:
You want to make a backup of the Windows registry.
Solution:
Making a backup of the Windows registry lets you restore the registry if you want to reverse changes that you make while editing it.
NOTE: Symantec provides the following information as a convenience and is not intended to replace information from Microsoft.
1. Click Start, and click Run. The Run dialog box appears.
2. Type regedit and then click OK. The Registry Editor opens.
3. Select My Computer at the top of the left pane.
4. Click Registry, and then click Export Registry File (Windows 95/98/Me/NT/2000), or click File, and then click Export (Windows XP).
5. Follow the instructions for your operating system (the dialog box that you see may vary slightly from what is shown here):
o Windows 95/98/NT
1. Select "Desktop" in the "Save in" box of the dialog box.
2. In the File name box, enter a name that you will remember, such as registrybackup.
3. Click Save. The file is saved to your Windows desktop.
o Windows Me/2000/XP
1. Click the Desktop icon.
2. In the File name box, enter a name that you will remember, such as registrybackup.
3. Click Save. The file is saved to your Windows desktop.
It does go from 3 to 6 just the picture is missing
6. Continue editing the registry if you have been instructed to do so.
CAUTION: Do not double-click the backup file that was placed on the Windows desktop except to undo the changes that you made to the registry. We suggest that you keep the backup file for a week or so until you are sure that the changes that you made have not caused any problems.
