Question

How do I backup my Windows Registry?

Answer

Before you make changes to a registry key or subkey, you should export or make a backup copy, of your registry.  You can save the backup copy to a location you specify, such as a folder on your hard disk or a removable storage device. If you make changes that you want to undo, you can import the backup copy.

Open the Registry Editor: 

·         Windows 7 & Vista:  Start button > type regedit into the search box > Enter;

·         Windows XP:  Start button > Run > type regedt32 > Enter;

o    If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

On the top menu line, click on File >Export

Select a location to save the file and in the File Name box enter a name;

In the Export Range section, click on All;

Click Save.
